Purpose: The Study of vaccination for infants and children business in Primary Health Care Posts from 1980 to 2009. Method: look for national essential vaccination look for the change of vaccination by the times in Primary Health Care Posts and the rate of vaccination for infants and children by a administrative report statistics survey of a vaccine delivery system of Public health care institutions investigation about assistance details of vaccination cost in order to raise the rate of vaccination for infants and children. Results: In 1980s, there are many infants and children management object, but now there are rapidly decreasing infants and children management subject of a Primary Health Care Post because of rural exodus phenomenon of 1990's and a low birthrate of 2000's. Currently, the infants and children that registed, and managed to a Primary Health Care Post is most multi-cultural families. A multi-cultural family assistance program is provided these infants and children to the objects. Conclusions: Infant vaccination execution in Primary Health Care Posts showed to high vaccination rate because the prevention of vaccination delay or omission of the interior child who raised geographical accessibility to object sons nowadays it difficult to management of transportation of vaccine and storage management for a little shroud objects limited and management of inoculation business in quality. A main problem is as follows. There are a little vaccine transportation, trouble of proper temperature maintenance of a storage process, and having a lot of vaccine abolition as a little objects, educational training shortage of health care practitioner regarding to execute an inoculation. Therefore, vaccination business needs measures for management in quality in Primary Health Care Posts.

The morphological changes of primary solid particles as a function of process time on hypereutectic Al-15.5wt%Si alloy during semi-solid state processing with a shear rate of $200s^{-1}$ are studied. In this alloy, it was observed that primary Si crystals are fragmented at the early stage of stirring and morphologies of primary Si crystals change from faceted to spherical during isothermal shearing for 60 minutes. To understand the role of Al dissolved in the primary Si crystal by shear stress at high temperature, lattice parameters of the primary Si crystals are determined as a variation of high order Laue zone(HOLZ) line positions measured from convergent beam electron diffraction(CBED) pattern. The lattice parameter of the primary Si crystal in the rheocast Al-15.5wt%Si alloy shows tensile strain of about 5 times greater than that of the gravity casting. Increase of the lattice parameter by rheocasting is due to the increased amount of Al dissolved in the primary Si crystal accelerated by shear stress at high temperature. The amounts of solute Al in the primary Si crystal are measured quantitatively by EPMA method to confirm the CBED analysis.

Objectives: The purpose of this study is to examine the effects of symptoms of dementia elderly on the primary caregiver's depression. In addition, moderating effect of family support was examined. Based on the results, the necessity for intervention in the level of social welfare as a way to mitigate primary caregiver's depression was suggested. Method: In order to accomplish these purposes, a total of 197 who are spouse and adult-children of dementia elderly using day care facilities or services in Seoul, Gyeonggi, Busan province, South Korea were utilized. Data were analyzed by frequency analysis and descriptive statistics, regression model analysis with SPSS 18.0. Results: In case of analysis results, the mean value was reported 0.9 out of four point about primary caregiver's depression and the mean value of family support was reported 3.34 out of five point. And besides, the analysis result of dementia elderly's symptoms showed that prevalence of depression/dysphoria were 62.2%, prevalence of aberrant motor were 61.3%, prevalence of apathy/indifference were 56.6%. Crucial findings are as follows: the symptoms of dementia elderly was significantly associated with the primary caregiver's depression. At the same time, family support significantly influenced lower level of the primary caregiver's depression. While, in the relationship between the symptoms of dementia elderly and the primary caregiver's depression, family support has a moderation effect by important protection factor. Conclusions: From these findings, the necessities to provide the care service for dementia elderly to help improve symptoms of dementia as well as the policy and service to manage the mental health of the family as primary caregiver were suggested. Also, the necessities to provide the family therapy program to improve the relationship with family members were suggested.

In cognitive radio networks, acquiring the position information of the primary user is critical to the communication of the secondary user. Localization of primary users can help improve the efficiency with which the spectrum is reused, because the information can be used to avoid harmful interference to the network while simultaneity is exploited to improve the spectrum utilization. Despite its inherent inaccuracy, received signal strength based on range has been used as the standard tool for distance measurements in the location detection process. Most previous works have employed the path-loss propagation model with a fixed value of the path loss exponent. However, in actual environments, the path loss exponent for each channel is different. Moreover, due to the complexity of the radio channel, when the number of channel increases, a larger number of RSS measurements are needed, and this results in additional energy consumption. In this paper, to overcome this problem, we propose using the Bayesian compressive sensing method with a calibrated path loss exponent to improve the performance of the PU localization method.

Objectives and Method : In this study, I have investigated what kind of primary factors detennine the apoplexy prognosis, and the method of the function assessment about the apoplexy by inquiry into the literature on this subject Results and Conclusions : 1. The primary factors to have an effect upon the appoplexy are : the location of Pungsa; whether five organs ki is existent or not; pulse feeling; tongue condition; whether or not the patient produces stool or urine; for males, the left side; for females, the right side ; whether or not the patient sweats; consciousness; vital signs; and the region and size of disease and brain hernia. 2. MBI is often used because it is considered to be objective, simple, and highly reliable. But its absence of a legal recognition assessment is a major incongruence. 3. Inclusive and standard assessment are key points in the reinforecement by AM of legal recognition assessment, but it takes a lot of time and is not endowed with adding an extra weight and is vague to the division between the communication and social recognition grade. 4. AI is useful and easy to evaluate the mental ability, the capacity for locomotion and the daily activities inclusively.

This paper reports the application of the PSTAR(Primary and Secondary Terms Analysis and Henormalization) method to a thermally massive passive solar house located in Daejeon, Korea. The house has approximately $156m^2$ of living area with 3 bedrooms and a living room, which embodies many passive solar features for energy conservation. The primary concern of this work was to properly evaluate the thermal behavior of a thermally massive building structure using the PSTAR method. Results show close agreements between the measured and renormalized values in most cases in which the simulation results from the audit description of the house deviate somewhat considerably.

A dynamic nanoindentation method was applied to study an Fe-18 at.% Gd alloy as a neutron-absorbing material prepared by vacuum arc-melting and cast in a mold. The Fe-18 at.% Gd cast alloy had a microstructure with matrix phases and an Fe-rich primary dendrite of $Fe_9Gd$. Rietveld refinement of the X-ray spectra showed that the Fe-18 at.% Gd cast alloy consisted of 35.84 at.% $Fe_3Gd$, 6.58 at.% $Fe_5Gd$, 16.22 at.% $Fe_9Gd$, 1.87 at.% $Fe_2Gd$, and 39.49 at.% ${\beta}-Fe_{17}Gd_2$. The average nanohardness of the primary dendrite phase and the matrix phases were 8.7 GPa and 9.3 GPa, respectively. The fatigue limit of the matrix phase was approximately 37% higher than that of the primary dendrite phase. The dynamic nanoindentation method is useful for identifying local phases and for analyzing local mechanical properties.

The present study develops a method for directly measuring the temperature field in the primary deformation zone with a high spatial resolution during 2-D orthogonal machining. This is enabled by the use of a high-speed, charge-coupled device (CCD) based, infra-red (IR) imaging system which allows characteristics of the temperature field such as the location and magnitude of the highest temperature and temperature gradient in the primary deformation zone to be identified. Based on these data, the relation between the machining temperature and the cutting conditions is investigated.

The dynamic resistance monitoring in primary circuit or T/C is one of the important issues in that in-process and real time quality assurance of resistance spot weld is needed to increase the product reliability. It is well known that tile dynamic resistance curve gives us very useful information about nugget growth and weldability. In the present paper, a new dynamic resistance detecting method is presented as a practical manner of weld quality assurance using instantaneous current and voltage measured by primary circuit. Primary dynamic resistance patterns are basically similar to those of the secondary, but there is evident advantage such as no extra devices are needed to obtain the quality assurance index and eventually feedback control will be possible caused by T/C based monitoring system.

The dynamic resistance monitoring is one of the important issues in that in-process and real time quality assurance of resistance spot weld is needed to increase the product reliability. Secondary dynamic resistance patterns, as a real manner, are hard to adapt those factors in real time and in-plant system. In the present study, a new dynamic resistance detecting method is presented as a practical manner of weld quality assurance at the primary circuit. By the correlation analysis, it is found that the primary dynamic resistance patterns are basically similar to those of the secondary. Various dynamic resistance indices are characterized with the primary curve. And quality of the weld, like the tensile shear strength, is estimated using adaptive neuro-fuzzy estimation system which is consisted of the Sugeno fuzzy algorithm. Through the fuzzy clustering and parameter optimization, real time weld quality assurance system with less efforts is proposed.
