The purpose of this study was to examine the relationship between social networks and perceived self-competence. The subject were 350 third and sixth graders selected from a public elementary school in Seoul. The children were administered the Pattison Psychosocial Network Inventory and The Self Perception Profile for Children. Three major questions are addressed; l)age changes 2)sex differences, and 3) the relation between the characteristics of social networks and self-perceived competence. Data were analyzed by pearson's product moment correlation, one-way ANOVA. Proportion measures were also used since they had allowed for the observation of relationship between two subsets of people within given categories(e.g.,the number of relatives divided by the number of relatives plus nonrelatives). The effects of age and sex of child on the number and daily contact with kin, nankin, peers, adults, males, and females were found. Sixth graders had a larger number of adults than third graders. While children had a greater number of adults than peers, they had more contact with peers than with adults in their network. It was found that boys had greater number of people in their network than girls. And boys had a larger number of and more contact with males, and girls had a larger number of more contact with females. The structure of childrens' social networks structure were correlated with perceived self-competence.

This study attempted to measure personality changes in collegiate nursing students as a result of their psychiatric nursing practice. The study population consisted of 310 students in 8 colleges of nursing in Korea, 96 with psychiatric practice, 103 with other clinical practice and III without clinical practice experience. The objectives of the study were to identify: 1. The self-actualization scores of nursing students resulting from psychiatric nursing practice. 2. The self-actualization scores of nursing students resulting from other clinical nursing practice. 3. The difference between scores for students with clinical practice experience and those without experience. 4. The relevance between self-actualization and sibling order. 5. The relevance between self- actualization and religion. 6. The coefficiently scores for students before and after clinical practice. The instrument used was the Personal Orientation Inventory (POI), developed by Shostrom. It provides a measure of values and behavior which are thought to be of importance in the development of self- actualization. The main findings of the study were as follows: 1. There was a significant difference in the Time Competence, Self Regard, and Nature of Man scales resulting from psychiatric nursing practice. 2. There was a significant difference in the Inner Directed, Existentialist, Feeling Reactivity, Spontaneity, Nature of Man and Capacity for Intimate Contact scales resulting from other clinical nursing practice. 3. There was a significant difference in the Inner Directed, Feeling Reactivity, Spontaneity, Self- Regard and Capacity for Intimate Contact scales between students with clinical practice and those without practice. 4. There was a significant difference in the Self-Acceptance scale for both the eldest and the youngest siblings. 5. There was a significant difference in the Time Competence, Inner Directed, Existentialist, Self-Acceptance and Capacity for Intimate Contact scales for middle and youngest siblings, 6. There was a significant difference in the Existentialist scale between students with a religion and those without one. 7. There was a significant difference for students without a religion in the Time Competence, Inner Directed, Self-Regard, Nature of Man, and Capacity for Intimate Contact scales after clinical practice. 8. There was a significant difference for students, with a religion in the Inner Directed, Existentialist, Spontaneity, and Nature of Man scales after clinical practice. 9. There was a significant difference for students in the Self- Actualizing value, Spontaneity, Nature of Man and Synergy scales according to whether their parents had a religion or not. 10. Before and after practice, significantly different correlations were found between the Time Competence and Capacity for Intimate Contact scales : the Inner Directed and Existentialist scales ; the Self- Actualizing Value and the Feeling Reactivity, Spontaneity, Self-Regard and Nature of Man scales : the Feeling Reactivity and Acceptance of Aggression scales: the Spontaneity and the Self-Regard and Nature of Man scales; and between the Self-Regard and Nature of Man scales.

Purpose: This study was performed to investigate the quantities of three neo-maternal exposures; visiting frequency, auditory contact and physical contact, and to examine the relationship between the quantities of each exposure and maternal attachment, maternal self-esteem and postpartum depression in 40 mothers of NICU babies during the first week in the NICU. Method: Each neo-maternal exposure was counted at every mother's visit to the newborn and maternal attachment, maternal self-esteem and postpartum depression were measured using the maternal attachment inventory, the maternal self-report inventory and Edinburgh Postpartum Depression Scale (EPDS) on the first and seventh day in the NICU. Result: The Mean of each neo-maternal exposure was 8.77(2.81) for the visiting frequency, 5.82(3.66) for the auditory contact and 5.60(2.89) for the physical contact during 7 days in the NICU. No significant changes were found in the scores of maternal attachment, maternal self-esteem and postpartum depression between the first and the seventh day in the NICU. The quantities of neo-maternal exposures were positively related to the scores of maternal attachment and maternal self-esteem but not related to postpartum depression. Conclusion: The results of the study suggest the lack of early neo-maternal exposure in cases of NICU hospitalization negate its beneficial effects on maternal psychological well-being in increasing maternal attachment and self-esteem. More efforts are neededfor the neo-maternal interaction and the reevaluation of NICU visitation hours in order to promote maternal-infant interaction.

This research was designed to evaluate the effect of need and of demographic variables of adult women on the conformity and individuality in the selection of clothes. 1. There are factors which have effect on variables of need. Marriage status, household type, age have effect on safety need, household type and age have effect on belongingness and love need. Household type and native community have effect on self-esteem need, household type, native community, school career, frequency of contact with mass media have effect on need for self-actualizing. Native community have effect on aesthetic need, and school careers have effect on the desires to know and to understand. 2. Self-esteem need, belongingness and love need, safety need, need for self-actualizing, aesthetic need, frequency of contact with mass media and income as demographic variables are directly related with conformity of clothing. Age, marriage status, native community, household type, school career are indirectly related with conformity of clothing. 3. Self-esteem need, need for self-actualizing, aestheitic need, desires to know and to understand, belongingness and love need, frequency of contact with mass media, household type have direct effect on the individuality of clothing.

A 1.8V $650{\;}\textrm{mm}^2$ 4Gb DRAM having $0.10{\;}\mu\textrm{m}^2$ cell size has been successfully developed using 0.11 $\mu\textrm{m}$DRAM technology. Considering manufactur-ability, we have focused on developing patterning technology using KrF lithography that makes $0.11{\;}\mu\textrm{m}$ DRAM technology possible. Furthermore, we developed novel DRAM technologies, which will have strong influence on the future DRAM integration. These are novel oxide gap-filling, W-bit line with stud contact for borderless metal contact, line-type storage node self-aligned contact (SAC), mechanically stable metal-insulator-silicon (MIS) capacitor and CVD Al process for metal inter-connections. In addition, 80 nm array transistor and sub-80 nm memory cell contact are also developed for high functional yield as well as chip performance. Many issues which large sized chip often faces are solved by novel design approaches such as skew minimizing technique, gain control pre-sensing scheme and bit line calibration scheme.

We investigated strength degradations from cyclic contact fatigue in self-toughened glass-ceramics. Hertzian indentation was used to induce cyclic contact load. Dynamic fatigue was also performed with changing stress rates from 0.01 to 10000 MPa/sec. After that, strength data and fracture origins were analysed. As the number of contact cycles increased or stressing rate decreased, severe strength degradation occurred by as much as 50% because of radial cracks developed from microcrack coalescence.

The wettability of TiO2 layers is controlled by forming highly ordered arrays of nanocones using nanopatterning, based on self-assembly and dry etching. Nanopatterning of TiO2 layers is achieved via formation of self-assembled monolayers of SiO2 spheres fabricated using the Langmuir-Blodgett technique, followed by dry etching. Compared to a thin film TiO2 layer, the nanopatterned TiO2 samples show a smaller static water contact angle, where the water contact angle decreases as the etching time increases, which is attributed to the Wenzel equation. When TiO2 layers are coated by 1H,1H,2H,2H-perfluorooctyltrichlorosilane, we observed the opposite behavior, exhibiting superhydrophobicity (up to contact angle of $155^{\circ}$) on the nanopatterned TiO2 layers. Self-assembled nanopatterning of the TiO2 layer may provide an advanced method for producing multifunctional transparent layers with self-cleaning properties.

Impedance control is recognised as one of the most proper control scheme to carry out the assembly tasks, since it can control the dynamic relationship between the manipulator and environment directly. However, it is well known that the contact force cannot be controlled directly using the impedance control. Also impedance parameters should be properly defined depending on the task to be performed. We propose a new position based impedance control, which has self-adjusted impedance parameters and can control the contact force explicitly, Impedance parameters, as time-varying parameters, are adjusted automatically based on the measured contact force and the position error during the task. A proposed algorithm was implemented on the peg-in-hole task with the industrial manipulator. We shows the effectiveness of proposed control method experimentally.
