  • Supporting object group on distributed object system give merits such as load balancing, fault tolerance and high availability. In this paper, we describe a CORBA ORB that has been designed to support object group based on active replication. The ORB supports the operational model in which it uses the IIOP for communication between client and server and total ordered multicast protocol for consistency control among group members. And through extension of ORB, it provides functions required for support of object group. Since it provides transparency of object replication, the ORB is interoperable with the existing CORBA products. It make possible for existing server application to be easily extended to application supporting object group as adding interface functions which should be used for building applications is minimized. A prototype is implemented, and performance of the replicated object group is tested and compared with a single object invocation.

  • The purpose of this paper is to compare two approach to assessment of coping patterns. The sampling method was a purposive sampling technique. The study participants were out patients 113 of rheumatoid arthritis center of one University hospitals in Seoul. Datas were collected from Nov. 13 to Nov. 24, 1995. The instruments used for this study were Graphic Rating Scales of pain, The Beck Depression Inventory and Coping Patterns tool. The collected data were analyzed for frequency, means, SD, factor analysis., Pearsons' correlations and ANOVA. The results were summerized as follows ; 1. When raw scores were used : there were not correlation in all three coping patterns. 2. When relative scores were used : there were significantly correlated in all three coping patterns. 1) Active coping and Positive-cognitive coping (r=-0.352, p< 0.0001) 2) Positive-cognitive coping and Negative-cognitive coping (r=-0.594, p< 0.0001) 3) Active coping and Negative-cognitive coping(r=-0.544, p< 0.0001) The results of this research with relative scales provided more insight into the correlation in all three coping patterns. 3. Pearsons' Correlations were computed for each coping pattern, age, pain level, duration of pain and BDI. 1) Using raw score : (1) Active coping was significantly related to pain level(sensory score ; r=0.268, p<0.05, affective score ; r=0.266, p< 0.05) (2) Positive-cognitive coping was significantly related to age (r=-0.252, p< 0.05), pain level (sensory score ; r= -0.244, p< 0.05) (3) Negative-cognitive coping was significantly related to depression level (r=0.312 p< 0.0001). 2) Using relative score (1) Active coping was significantly related to pain level(sensory score ; r=0.299, p<0.05, affective score ; r=0.246, p< 0.05) (2) Positive-cognitive coping was significantly related to age (r= -0.187, P< 0.05), pain level (sensory score ; r=-0.317, p<0.0001, affective score : r=-0.305, p<0.0001) and depression level(-0.339, p<0.0001)) (3) Negative-cognitive coping was significantly related to depression. level(r=0.313, p<0.0001). 4. When raw and realtive coping scores were compared to those of age groups, religious groups and BDI level(high, middle, low) ; 1) Using raw score : (1) Active coping : there were not significantly difference (2) Positive-cognitive coping ; 20-39 age group and 50-59age group had significantly higher scores than over 60age group. BDI-low level group had significantly higher scores than other groups. (3) Negative-cognitive coping : 20-39age group and over 60age group had significantly higher scores than 40-49age group. Non-religious group had significantly higher scores than christian group. BDI-high level group had significantly higher scores than other groups. 2) Using relative score : (1) Active coping : over 60 age group had significantly higher scores than 20-39 age group and 40-49age group had significantly higher scores than 20-39 age group (2) Positive-cognitive coping ; 40-49age group, 20-39age group and 50-59age group had significantly higher scores than over 60age group. Christian group had significantly higher scores than non-religious group. BDI-low level group had significantly higher scores than other groups. (3) Negative-cognitive coping ; Non-religious group had significantly higher scores than christian group and buddhistic group. BDI-high level group had significantly higher scores than other groups. The current data suggest that relative scores may yield a different perspective on coping patters than raw scores. The use of relative scores reveals the relation clearly, without its being blurred statistically by the effect of other coping strategies or being relegated to a partial correlation. The use of relative scores holds promise for delineating the relations between ways of coping and health-related behavior.

  • In this study, a novel group-indexed orthogonal frequency division multiplexing index modulation (OFDM-IM) scheme is proposed to achieve a tradeoff between spectral efficiency (SE) and bit-error-rate (BER) performance. In the proposed scheme, the total subcarriers in a group are divided into subgroups, and additional bits are transmitted by subgroup indexing, unlike the conventional OFDM-IM scheme, which uses index bits to select active subcarriers. With the proposed scheme, the additional degree of freedom provided by the number of active subgroups selected provides a tradeoff between spectral efficiency and BER performance. Decoding is performed in steps to reduce computional complexity in the decoder design. Simulaton results show that the number of active subgroups selected influences the proposed scheme's performance in terms of energy efficiency, spectral efficiency, and BER performance.

  • Purpose: The purpose of this study was to evaluate the effects of Doula support during labor on anxiety, labor pain, and perceived childbirth experience of primiparas. Method: Of 65 primiparas who were hospitalized in LDR from March 1 to September 30, 2007. 32 women were placed in the Doula group and 33 in the control group. VAS was used to measure the degree of labor pain and anxiety in the latent, active, and transitional phases. Perceived childbirth experience was measured within 2 hours after birth. Results: The Doula group had a significantly lower anxiety level than the control group in the active phase (t=-2.13, p=.04) and the transitional phase (t=-3.99, p=.000). The degree of labor pain of the Doula group was significantly lower than that of the control group for the active phase (t=-3.10, p=.003) and the transitional phase (t=-7.24, p=.000). Also, There was no significant difference in perceived childbirth experience between the two groups (t=.19, p=.85). Conclusion: The results of this study show Doula support in LDR decreases not only anxiety of primiparas but also labor pain in the active and transitional phases. Therefore Doula support by nurses in LDR can be a useful intervention during childbirth.

  • Purpose: The purpose of study was to compare depression, marital intimacy, sexual function and quality of life between a group of sexually active women and a group of women who were sexually inactive. All of the women were post-menopausal married women. Methods: Post-menopausal married women (n=395) of 40 to 59 years old participated in the study. Data were collected through self-report questionnaires which included items on general characteristics, and tools on depression (CES-D), marital intimacy (MIQ), sexual function (FSFI), and quality of life. Data were analyzed using descriptive statistics, t-test, $X^2-test$, ANCOVA, and Pearson correlation coefficients. Results: About 42% of the participants were identified as sexually inactive. Marital intimacy, sexual function, and quality of life in the sexually active group were significantly higher than the inactive group (F=17.12, p<.001; F=36.86, p<.001; F=16.78, p<.001). Depression scores in the sexually active group were significantly lower than in the inactive group (F=14.64, p<.001). Also, there was a significant relationship of depression, marital intimacy, and sexual function to quality of life in both groups. Conclusion: The results of this study indicate that health professionals need to counsel and provide a psychosexual approach especially when caring for post-menopausal married women who are sexual inactive.

  • This study investigated the relationship between style of purchase behavior and search information, attitude, and behavior for energy saving. In addition, this paper classified several consumer groups based on their different styles of purchase behavior and investigated whether those groups differ in attitude and behavior for energy saving. The following is a summary of the main results. First, consumers were classified according to style of purchase behavior into a rational consumer group, a fashion- or brand-oriented group, a group uninterested in consumption, and a neutrally oriented group. Second, there were no significant differences among the four consumer groups in the amount of information search and the level of communication with other consumers related to energy-saving information; however, there were significant differences in terms of the information sources used. For example, the neutrally oriented group was more likely to use more objective information sources. Third, the level of attitude toward energy saving was more likely to be active when consumers were old and rational. Consumers with a high income, education and experience in energy saving, and an active attitude were more likely to be active in energy saving, especially in the disposal stage of purchase. Finally, attitude toward energy saving was the most influential factor in the level of energy-saving behavior.

  • This study investigates the fashion lifestyles and the effect on clothing purchase behavior by female consumers living in Mumbai India. Data were collected from 129 Indian women in their teens to thirties living in Mumbai and were analyzed by factor analysis, cluster analysis, one-way ANOVA, Duncan test, ${\chi}^2$-test, frequency analysis using SPSS 12.0. The results of this study are as follows. Five factors of fashion lifestyle are identified: fashion consciousness, price orientation, advertisement/brand orientation, being aware of others, and tradition orientation. Female consumers were classified into four groups based on fashion lifestyle factors: display/brand oriented group, active profit seeking group, fashion oriented group, and a tradition oriented group. There were significant differences among the fashion lifestyle groups on five criteria (latest fashion, price, commonality with existing clothing, size, and the distance to the store) out of the 13 criteria. The display/brand oriented group showed high scores on the latest fashion and size. The active profit-seeking group generally showed high scores on all five factors. The fashion oriented group showed high scores on latest fashion and commonality with existing clothing when buying clothes. Finally, the tradition oriented group showed high scores only on the distance to the shop, while they (the tradition oriented group) showed low scores on the other criteria. The examination on the actual conditions of clothing purchase among fashion lifestyle groups showed that only the monthly expenditure for clothing is significantly different. The display/brand oriented group and active profit seeking group spent more on clothing than the other two groups.
