Family and parents which serve as a primary group for the children's development also play important role in their cerebral palsy children's treatment. This study wants to know how the parents' participation in their children's physical therapy and satisfaction degree have an impact on their children's improvement of the motor function. For that purpose, a home made self filling survey was conducted of 156 cerebral palsy children's parents whose children were treated in 4 university general hospitals and 3 welfare centers from the 1st of April 2004 to the 31th of march 2005. The gross motor function was employed to evaluate the cerebral palsy children's motor function improvement. In this study, those questioned were divided into two groups according to the time of treatment. 'Group A' is consist of the patients whose parents attended to the treatment more than one hour at home. The patients who belonged to 'Group B' were treated less than one hour at home. The general features of the cerebral palsy children and their parents and the characteristics of their physical disability, the parents' participation and their satisfaction degree were examined by survey. Evaluating the difference between two groups' motor function according to their parents participation degree in the physical therapy leads to the following results. First, 'Group A' was better than 'Group B' in their satisfaction degree with the physical therapy and participation degree. Statistically 'Group A' was superior to 'Group B' in the requirements of the information and education for the children with cerebral palsy. Second, after two months of treatment, 'Group A' showed more statistically significant improvement than 'Group B' in every items as like lying in item 1, sitting in item2, crawling and kneeling in item 3, standing in item 4, walking,running, jumping in item 5. Third, parents' participation in physical therapy and satisfaction degree have some relevance to their children' motor function improvement. The satisfaction degree is related to motor function like crawling and kneeling in item 3, walking,running, jumping in item 5. It is showed that the parents' participation degree and information about handicapped children.

We present a theoretical investigation on the etching of an Al solid by $SiCl_4$ molecules at a collision energy of 600 eV. The classical trajectory method is employed to calculate Al etching yields, degree of anisotropy, kinetic energy distribution and angular distribution. The calculated results are compared with the reaction of a Cu solid by $SiCl_4$. The major products of the reaction are aluminum monomers and dimers together with considerable quantities of multimers. The Al solid shows better etching yield and better anisotropy than the Cu solid. This is consistent with the problem in the CMOS micro-fabrication of the CuAl and CuAlSi alloys. The relevance of these calculations for the dry etching of CuAl alloy is discussed.

This paper presents the two combination methods for leakage current reduction in photovoltaic system PCS. The leakage current in the photovoltaic system generated from the parasitic capacitance existing between the photovoltaic system and ground relevance to common mode voltage caused by PWM switching. Firstly, Leakage current reduced by a PWM method using two carriers with 180-degree phase different. Secondly, the leakage current is more reduced by connecting LCL filter to the mid-point of DC link. This combining method is revealed in PSIM simulation with 1 uF parasitic capacitance.

The measurement of informatization program effectiveness continues to be a central concern of both academics and practitioners. However, most studies of it have been inclined too heavily toward testing validity and reliability of evaluation measure to strengthen the theoretical rigor. Drawbacks of this approach have been pointed out as being unsuitable for evaluating the effectiveness of informatization program due to lack of practical relevance. The paper comprises four sections to solve the problem. 1) Through literature review of theoretical conceptual models in IS effectiveness and the domestic and foreign cases on informatization program, we establish the evaluation framework which consists of evaluation phases, 6 evaluation areas, and 22 evaluation items, and developed evaluation measures of each items. 2) Different researchers have addressed different aspects of attribute of measure. With comparing them to each other, 3 mutually exclusive criteria on coincidence analysis(usability of measurement. reliability of measurement. and validity of content) are identified. 3) Data are gathered from respondents in informatizaiton program-related organizations such as policy agency, management agency, support agency, and recipient agency. 4) The degree of coincidence of each evaluation measure are analyzed by course of an coincidence analysis procedure, which includes the reliability test, arithmetical test, and criteria validity test. The academic implication of this study is that researchers can gain an insight into the coincidence analysis to approach the problem of deciding on an indicator of performance for informatization program. There is also practical implication for applying the potential means of improving the practical relevance of conducting evaluating the informatization program.

Alcoholic liver cirrhosis (ALC) is caused by chronic alcohol overconsumption and might be linked to dysregulated immune responses in the gut-liver axis. However, there is a lack of comprehensive research on levels and functions of innate lymphocytes including mucosal-associated invariant T (MAIT) cells, NKT cells, and NK (NK) cells in ALC patients. Thus, the aim of this study was to examine the levels and function of these cells, evaluate their clinical relevance, and explore their immunologic roles in the pathogenesis of ALC. Peripheral blood samples from ALC patients (n = 31) and healthy controls (HCs, n = 31) were collected. MAIT cells, NKT cells, NK cells, cytokines, CD69, PD-1, and lymphocyte-activation gene 3 (LAG-3) levels were measured by flow cytometry. Percentages and numbers of circulating MAIT cells, NKT cells, and NK cells were significantly reduced in ALC patients than in HCs. MAIT cell exhibited increased production of IL-17 and expression levels of CD69, PD-1, and LAG-3. NKT cells displayed decreased production of IFN-γ and IL-4. NK cells showed elevated CD69 expression. Absolute MAIT cell levels were positively correlated with lymphocyte count but negatively correlated with C-reactive protein. In addition, NKT cell levels were negatively correlated with hemoglobin levels. Furthermore, log-transformed absolute MAIT cell levels were negatively correlated with the Age, Bilirubin, INR, and Creatinine score. This study demonstrates that circulating MAIT cells, NKT cells, and NK cells are numerically deficient in ALC patients, and the degree of cytokine production and activation status also changed. Besides, some of their deficiencies are related to several clinical parameters. These findings provide important information about immune responses of ALC patients.

The purpose of this study was to find out the degree of satisfaction of body image and sex-role identity of primary school boys and girls and to examine their relevance between two sex groups. The data from study would be useful for mapping out some measures for school health education. Two hundred and forty five(245) students of 6th grade from 5 different primary schools in Seoul city and Gyonggi Province were selected for the study. The meaningful difference among demographic sociological characteristics between boys and girls has been shown to be in religion($x^2$=6.705, p=.044), the order of siblings($x^2$=7.455, p=.024), mother's academic career ($x^2$=6.705, p=.035) and the levels of living ($x^2$=4.108, p=.043). In the frequency distribution of sex-role identity, boys and girls were revealed as : undifferentiated 41.0%, 36.4%; as androgynous 24.8%, 25.8% respectively. Boys have masculinity (23.1%), on the other hand girls more feminity (22.7%). The meaningful difference of the degree of satisfaction of body image depends on father's ag(t=3.029, p=.050), mother's occupation(t=2.878, p=.023), home atmosphere(t=9.056, p=.000), level of livin(t=2.216, p=.028), academic achievements(t=4.580, p=.011). Masculine sex-role identity has shown its meaningful difference in mother's academic background(t=7.042, p=.001), academic achievements(t=14.963, p=.000). Feminine sex-role identity according to general characteristics shows meaningful difference in gender(t=2.683, p=.008), the order of siblings(t=3.019, p=0.51), father's academic career(t=5.558, p=.004) mother's academic background(t=7.676, p=.001), mother's occupation (t=3.405, p=.010), home atmosphere(t=4.492, p=.012), school performance(t=16.774, p=.000). Sex-role identity influences on the degree of satisfaction of body image as the relation bet ween the degree of satisfaction of body image and sex-role identity is pro correlative.
