This study evaluated the effect of the nutrition education about infant feeding on the change of mother's knowledge, attitude and practice of weaning. The subjects consisted of treatment group (n=54) and control group (n=34). The treatment group participated in 6 times nutrition education and 5 times surveys. Nutrition education for weaning of the treatment group improved nutrition knowledge, attitude and practice in infant feeding. Before education, mean scores of control group and treatment group were 7.3 and 7.5 respectively but there was no significant difference. Both group got low score in a statement about weaning period, but they got good score in a statement about weaning method. After education, treatment group got better score(9.1) than control group(8.3) significantly (p<0.05). Treatment group was more desirable than control group specially in a use of Sun-sik, sugar, salt and weaning food mixed with formula after education (p<0.05). Practice of spoon feeding was more frequent in treatment group after education, however, control group used sugar and commercial weaning food more frequently than treatment group(p<0.05). Intake frequency of cow's milk and cookies of infants at age 9-12 month in control group was higher than treatment groups(p<0.01). Thus the nutrition education to mother seems to be effective in achieving desirable dietary behavior of infants.

Objectives: Cognitive-behavioral scientists have long been interested in how a pain patient's cognition such as locus of control relates to coping and adjustment. The present study examined the relationship of locus of control orientation to pain coping strategies, psychological distress and perceived pain intensity of patients with pain. Methods : Subjects were 96 patients with pain who visited pain clinic. All patients were administered the Multidimensional Health Locus of Control Scales, the Minnesota Multiphasic Personality Inventory, the Coping Strategies Questionnaire, and rating for perceived pain intensity, distress, and duration. Results : Correlational analysis revealed that patients who viewed outcomes as controlled by internality tended to have better ability to control and decrease pain. Also they tended to be less depressed and anxious. Regression analysis indicated that patients having a internal locus of control were more likely to use coping self-statement and reinterpreting pain sensation. Powerful others and chance locus of control orientation were predicted reliance on catastrophizing. Conclusion : The clinical implication of the present study is that cognitive factors of patients with pain such as locus of control influence emotional distress and coping. this study show that these factors should be applied to cognitive behavioral therapeutic intervention.

Objectives : Cash Flows from operating activities is the most important part of the cash flow statement and it serves as an important financing source. Accordingly, the purpose of this study is to examine the influence of the contents of cash flows from operating activities on the changes in borrowings. Methods : In this study financial data from 2011 to 2014 were used to analyz 36 general hospitals and 85 hospitals according to the index displaying variation against the previous year. Results : For general hospitals, borrowings in cash flow from financing activities increased as net income decreased; while depreciation etc increased in cash flow from operating activities. For hospitals, borrowings in cash flow from financing activities increased as the gain on disposition of tangible assets in cash flow from operating activities decreased. Conclusions : General hospitals need to control the management of borrowings and depreciation at the level of funding management; whereas hospitals need to manage of future cash forecasts for stability of operational funds.

Esterel is an imperative synchronous language well-adapted to control-intensive systems. When an Esterel program is translated to a circuit, the synchronizer of a parallel statement may be executed more than once in a clock; the synchronizer is called schizophrenic. Existing compilers cure the problems of schizophrenic parallel synchronizers using logic duplications. This paper proposes the conditions under which a synchronizer causes no problem in circuits when it is executed more than once in a clock. In addition we design a detection algorithm based on those conditions. Our algorithm detects schizophrenic parallel synchronizers that have to be duplicated in Esterel source codes so that compilers can save the size of synthesized circuits

Interactions of a humanoid with a human are important, when the humanoid is requested to provide people with human-friendly services in unknown or uncertain environment. Such interactions may require more complicated and human-like behaviors from the humanoid. In this work the arm motions of a human are discussed as the early stage of human motion imitation by a humanoid. A motion capture system is used to obtain human-friendly arm motions as references. However the captured motions may not be applied directly to the humanoid, since the differences in geometric or dynamics aspects as length, mass, degrees of freedom, and kinematics and dynamics capabilities exist between the humanoid and the human. To overcome this difficulty a method to adapt captured motions to a humanoid is developed. The geometric difference in the arm length is resolved by scaling the arm length of the humanoid with a constant. Using the scaled geometry of the humanoid the imitation of actor's arm motions is achieved by solving an inverse kinematics problem formulated using optimization. The errors between the captured trajectories of actor arms and the approximated trajectories of humanoid arms are minimized. Such dynamics capabilities of the joint motors as limits of joint position, velocity and acceleration are also imposed on the optimization problem. Two motions of one hand waiving and performing a statement in sign language are imitated by a humanoid through dynamics simulation.

The purpose of this study was to construct the Marital Relationship Enhancement Program based on PREP(Prevention and Relationship Enhancement Program), and to examine the effect of it for couples in the early marriage stage. To perform this program, six session of time-limited(two hour) were carried out experimental group. and subjects were assigned to experimental group(N=6 couples) and control group(N=6 couples). Scales of PREPARE II (PREmarital Personal And Relationship Evaluation), Couple Communication Scales and Commitment Scales were used as pre-post-follow instruments of this study. Major finding were as follows : 1. Marital Relationship Enhancement Program for couples in the early marriage stage has meaningful consequences for the improvement of participants' couple relationship. 2. Marital Relationship Enhancement Program had meaningful consequence for the improvement of participants' realistic expectation of marriage, communication and conflict resolution skills and leisure activities. These positive effects maintained at follow-up. However, it hadn't meaningful consequence for the improvement of participants' marital commitment. 3. Marital Relationship Enhancement Program had also meaningful consequence for the improvement of the wives' realistic expectation of marriage, communication and conflict resolution skills and leisure activities, of the husbands' communication and conflict resolution skills.

The structures of concern in this study are subject to two types of forces: dead loads from the acceleration imposed on the structures as well as the installed operation machines and the additional adjustable forces. We wish to determine the critical values of the adjustable forces when buckling of the structures occurs. The mathematical statement of such a problem gives rise to a constrained eigenvalue problem (CEVP) in which the dominant eigenvalue is subject to an equality constraint. A numerical algorithm for solving the CEVP is proposed in which an iterative method is employed to identify an interval embracing the target eigenvalue. The algorithm is applied to four engineering application examples finding the critical loads of a fixed-free beam subject to its own body force, two plane structures and one wide-flange beam using shell elements when acceleration force is present. The accuracy is demonstrated using the first example whose classical solution exists. The significance of the equality constraint in the EVP is shown by comparing the solutions without the constraint on the eigenvalue. Effectiveness and accuracy of the numerical algorithm are presented.
