The purpose of this study was to develop the couple breast-feeding education program and to investigate the effects of program on breast-feeding self-efficacy, spouse support and breast-feeding satisfaction of primipara. The 3 session(20-40 min/one day) the breastfeeding spouses education program was developed and a non-equivalent control group quasi-experiment design was used. Sixty-three participants were assigned to either the experimental group (n=32) or the control group (n=31). A pre-test and post-test were done to identify the effect of the program. Effects were tested using $x^2$-test, t-test. Scores for breast-feeding self-efficacy(t=3.44, p=.001), spouse support(t=3.03, p=.004) and breast-feeding satisfaction(t=3.64, p=.001) of the experimental group after program were significantly higher than the control group scores. The effects of the couple breast-feeding education program for elevating breast-feeding self-efficacy, spouse support and breast-feeding satisfaction of primipara were validated. Therefore, this program can be recommended for vigorous use in clinical practice.

The purpose of this study is to develop and to verify an effect of a group counselling program for children who are in need of improving social skills and relationships. In order to meet this goal, the study procedure was employed as follows: First, the literature review of studies on childrens in social welfare institutions was implemented. Second, to analyze need of staffs in facilities and to specify the present condition of children, 100 staffs were participated in basic investigation. The result of investigation revealed that social skill development programs should be held in form of total 11~12 sessions once or twice in a week, with 50~60 minutes per session. Third, based on the literature review and current situation investigation results, a program for improving social skills and competencies of children was developed. To verify the program, two groups composed of elementary children who are fourth grade to sixth grade were organized. The groups were a experimental group which was provided with a group counselling program and a control group with no program. The program was composed of twelve sessions throughout six weeks, and the subjects took social skill test after taking the program to verify educational effects. T-test were implemented to analyze difference of the test results of two groups statistically. As a result of a research, following major two findings were specified: (1) experimental group showed significant difference in the score of self-assertion, cooperation, and self-control, which indicates that the program was effective for social skill improvement: (2) according to the test result, the self-assertion, cooperation, and self-control skills were clearly improved. In conclusion, the program turned out to be an effective and a positive educational device to enhance social skills of the children. The program developing model were suggested to improve social skills of children in the state of family devision based on the study findings. The follow-up future studies should elaborate program models for various-aged children and for children with various learning styles. Furthermore, qualitative study method should be employed which can specify social attitude change of children.

There have been large concerns about survivability defined as the capability of a system to perform a mission-critical role, in a timely manner, in the presence of attacks, failures. In particular, One of the most important core technologies required for the design of the ITS(Intrusion Tolerance System) that performs continuously minimal essential services even when the computer system is partially compromised because of intrusions is the survivability one of In included the dependability analysis of a reliability and availability etc. quantitative dependability analysis of the In. In this Paper, we applied self-healing mechanism utilizing two factors of self-healing mechanism (fault model and system response), the core technology of autonomic computing to secure the protection power of the ITS and consisted of a state transition diagram of the ITS composed of a primary server and a backup server. We also defined the survivability, availability, and downtime cost of the ITS, and then performed studies on simulation experiments and two cases of vulnerability attack. Simulation results show that intrusion tolerance capability at the initial state is more important than coping capability at the attack state in terms of the dependability enhancement.

Because of self-enhancement motives, when involved in social comparison, many people generally value things that are related to themselves, with the representative example being possessions, which is known as the endowment (ownership) effect. However, there are times when someone else's possessions appear to be better than our own, even if they are the same things, which is known as the endowment effect reversal. The purpose of this study was to explore the moderating variable that regulates the endowment effect and the endowment effect reversal by confirming whether the value estimation of others' belongings differed through a regulatory focus as it was surmised that the regulatory focus would moderate the endowment effect of the self versus the others' ownership. Foreign participants were shown the currency of a country they were unfamiliar with and asked to estimate the value in their home country currency. It was found that when people thought the money was their own, people with a promotion focus estimated the value to be higher than people with a prevention focus. However, when they thought it was someone else's money, the regulatory focus moderating effect was not found to be significant, which suggested that the endowment effect may be strengthened or eliminated depending on the individual's regulatory focus. Based on these study results, the implications, limitations, and suggestions for follow-up studies are discussed.

The characteristics of polymeric thin-film transistors(TFTs) can be controlled by chemically modifying the surface of the gate dielectric prior to the organic semiconductor. The chemical treatment consists of derivative the tantalum pentoxide($Ta_2O_5$) surface with organic materials to form self-assembled monolayer(SAM). The deposition of an octadecyl-trichlorosilane(OTS), hexamethy-ldisilazone(HMDS), aminopropyltreithoxysilane(ATS) SAM leads to a mobility of $0.01\sim0.06cm2/V{\cdot}s$ in a poly-3-hexylthiophene(P3HT) conjugated polymer. The mobility enhancement mechanism is likely to involve molecular interactions between the polymer and SAM. These result can be used for polymer TFT's dielectric material.

Purpose: The purpose of this qualitative study was to understand the application of clinical reasoning throughout clinical and therapeutic knowledge of clinical pediatric physical therapists under physician prescriptions. Methods: Purposive sampling techniques were used in selection of nine clinical pediatric physical therapists in South Korea. Open and semi structured interviews were conducted, and were thoroughly examined and reviewed, followed by analysis of the clinical reasoning portion. Results: Pediatric physical therapists have been influenced by information gathering, physical function and evaluation of their patients, hypothesis-orientation, and re-evaluation and self-monitoring. Novice physical therapists were more dependent on physician prescriptions and parent's hope than the result of their own evaluation and critical pathway. Middle experienced pediatric physical therapists were more dependent on rapport with children and their parents. Highly experienced pediatric physical therapists were more reliant on hypothesis-orientation and self-monitoring. As reports on clinical experience of pediatric physical therapists have accumulated, clinical reasoning of pediatric physical therapists has been influenced by their experience, such as education, clinical pathology conference, their own clinical experience and rapport with patients and their parents than physicians' prescriptions. Conclusion: The findings of the current study are generally consistent with existing research on clinical reasoning. The results of the current study may be used by educators for enhancement of clinical reasoning abilities and knowledge of students or novices as well as development of a guide for use by suitable novices or students, and could provide important information for use in physical therapy practice and research.

The mobility in strained Si inversion layer on $Si_{1-x}Ge_x$ is calculated considering a quantum effect(subband energy and wavefunction) in inversion layer and relaxation time approximation. The quantum effect in inversion layer is obtained by using self-consistent calculation of $Schr\ddot{o}dinger$ and Poisson equations. For the relaxation time, intravalley and intervalley scatterings are considered. The result shows that the reason for the enhancement in mobility as Ge mole fraction increases is that the electron mobility in 2-폴드 valleys is about 3 times higher than that of 4-폴드 valleys and most electrons are located in 2-폴드 valleys as Ge mole fraction increases. Meanwhile, for the phonon-limited mobility the fitting to experimental data, Coulomb and surface roughness mobilities are included in total mobility, Deformation potentials are selected for the calculated effective field, temperature, and Ge mole fraction dependent mobilities to be fitted to experimental data, and then upgraded data can be obtained by considering nonparabolicity in Si band structure.

The device performance of nano-scale center-channel (CC) double-gate (DG) MOSFET structure was investigated by numerically solving coupled Schr$\"{o}$dinger-Poisson and current continuity equations in a self-consistent manner. The CC operation and corresponding enhancement of current drive and transconductance of CC-NMOS are confirmed by comparing with the results of DG-NMOS which are performed under the condition of 10-80 nm gate length. Device optimization was theoretically performed in order to minimize the short-channel effects in terms of subthreshold swing, threshold voltage roll-off, and drain-induced barrier lowering. The simulation results indicate that DG-MOSFET structure including CC-NMOS is a promising candidates and quantum-mechanical modeling and simulation calculating the coupled Schr$\"{o}$dinger-Poisson and current continuity equations self-consistently are necessary for the application to sub-40 nm MOSFET technology.

Purpose Through the provision of real time performance information about who is contributing and who is not in Electronic Brainstorming, prior studies evidenced a significant performance gain. However, it has been observed that the quantity-based performance feedback alone does not have enough restrictiveness to guide the performance behavior throughout the idea generation session. We included the notion of goal setting into the process performance feedback mechanism in an effort to regulate performance behavior and to better understand why individuals in Electronic Brainstorming are not obtaining enough stimulation benefits in the group interaction process. Design/methodology/approach We had developed real-time visual process performance feedback and modified to include goal setting. This mechanism visually displays individuals' performances two-dimensionally (quality for each idea vertically and quantity of ideas horizontally along with their goals). As individuals' contributions accumulate, the mechanism reveals performance histories by connecting the sequence of ideas in a time-series format, telling stories of individuals' performances. Then, we compared the performance outcome from this study with the outcomes from two prior studies (i.e., Jung et al., 2010 and Jung, 2014). Findings The results showed that the inclusion of goal setting into the process performance feedback solved the issue in the previous study. That was the lower than expected magnitude of performance enhancement of process performance feedback when compared to that of quantity-based feedback. It appears that goals as a motivational technique provide standards for systematic self-evaluation, serving as a cue to regulate performance behavior by strengthening the linkage between effort and performance. Thus, goals seem to set up a self-fulfilling prophecy, preconditioning better performance. However, the outcome still showed that its performance magnitude is unsatisfactory because the outcome of this study turned out to be close to the outcome of just quantity-based performance feedback in Jung et al.'s (2010) study.
