  • The purposes of this study were (1) to explore the stability of social acceptance when childen transferred from kindergarten to elementary school, and (2) to identify factors that predict children's social acceptance in new school environments. Twenty two children of 'J' kindergarten who were transfering to 'S' elementary school were sampled at the end of their kindergarten year. They were administered social acceptance tests, a school readiness test, and the simplified version of the Preschool Behavior Questionnaire. A sample of 135 children including the 22 children of 'J' kindergarten were administered social acceptance tests in the middle of the first grade of elementary school and questionnaires on their children's social experiences were completed by their parents. Social acceptance scores were found to be stable from kindergarten to elementary school. School readiness test scores and distractibility ratings by preschool teachers were moderately correlated with post-transition social acceptance. Among the social experiences variables, duration and number of preschool experiences were significantly correlated with social acceptance in the first grade of elementary school. There were no significant differences of social acceptance score according to the type of kindergarten.

  • The purpose of this study was to devise an Unconditional Self-Acceptance Development Program and examine the efficacy of the program on alleviating children's depression and improving psychological wellbeing. In order to test the efficacy of the developed program, Multidimensional Perfectionism Scale (MPS: Hewitt & Flett, 1991), Unconditional Self-Acceptance Questionnaire (USAQ; Chamberalain & Haaga, 2001), Children's Depression Inventory (CDI; Kovacs & Beck, 1977), and Psychological Well-Being Scale(PWBS: Seng Hee Lee, 1999) were used for pre- and post tests. The test results were analyzed using t-tests. Twelve elementary school students suffering from depression participated in eight sessions of the Unconditional Self-Acceptance Development Program, and then were compared with 13 children in the control group who did not receive the treatment. The result was as follows: the treatment group showed statistically significant improvement in unconditional self- acceptance, alleviated level of depression, and increased psychological wellbeing, in comparison with the control group. The findings of this study suggest that unconditional self-acceptance development program should be adopted as a new therapy program for children's depression and psychological wellbeing.

  • This paper reviewed and summarized the experimental studies conducted during last three decades to evaluate the structural integrity and to establish the acceptance criteria for piping system of nuclear power plants (NPPs) under seismic loading condition. These experimental studies contain the results of large-scale piping system tests under excessive seismic loading as well as standard specimen tests, simplified piping specimen tests, and piping components tests under simplified dynamic and cyclic loading. These would be useful as a basis for establishing integrity assessment procedure and acceptance criteria for piping systems of NPPs under beyond design basis earthquake (BDBE) conditions, and also could be used in planing the scope and direction of further related researches.

  • A reduced salt, dry-type bulgogi bibimbap with AF-343 was prepared, and the acceptance, antioxidant antimicrobiological safety were investigated. The acceptance of the reduced salt and the AF-343 added sample, RW, showed the highest value of 5.37 among the samples, but it did not differ significantly from the other samples of the standard sample group. The acceptances of the appearance, aroma, texture, and overall acceptance were not significantly different in all samples (p>0.05). In the DPPH radical scavenging activity, the values of SW and RW with the AF-343 were 15.05 and 14.77, respectively, which were significantly higher than the 9.57 and 10.42 obtained for SWO and RWO without AF-343, respectively (p<0.05). Pathogenic microorganisms tests that were either negative or not detected in any of the samples representing hygiene safety were met in the dried bibimbap against Escherichia coli, pathogenic microorganisms, and general bacteriological tests. The aerobic plate counts were 30.0 CFU/g, indicating that the dry type salt-reduced bibimbap containing AF-343 was within the safety range that meets the safety standards of microorganisms in the food code for commercialization. Therefore, high-quality dry-type reduced salt bibimbap with AF-343 is helpful for antioxidant action and effective for skin moisturizing and can be produced without affecting the taste and palatability.

  • This study was undertaken to develop the gap acceptance model of left-turn drivers on the major road at intersections. Typical unsignalized intersections on the two-lane and four-lane streets in Masan City were selected for the study intersection. For the gap distribution model, the lognormal, negative exponential, shifted negative exponential, and Gamma distributions were tested using the x2 and K-S tests. Based on the results for both streets, it was concluded that among the distributions tested the lognormal distribution represented the gap distribution best, followed by the shifted negative exponential distribution. Stochastic models of the gap-acceptance behavior of left-turn drivers on the major road at unsignalized intersections were programmed using SLAM Ⅱ, a simulation computer language. A stochastic model was selected for the gap-acceptance behavior to compare the results of the simulation with the observed data. The model assumes that a fixed critical acceptance gap is assigned to each left-turn driver based on a normal distribution and the gap distribution of the opposing traffic stream follows the shifted negative exponential distribution.

  • This paper deals with a group acceptance sampling plan for time truncated tests which are based on the total number of failures from the whole group assuming that the life time of an item follows the Dagum (inverse Burr) distribution. This study is developed when a multiple number of items as a group can be tested simultaneously in a tester. The minimum number of groups required for a given group size and acceptance number is determined such that the producer and consumer risks are satisfied simultaneously at the specified quality level, while the termination time and the number of testers are specified. Comparisons are made between the proposed plan and the existing plan on the basis of size of the groups. Two real examples are provided.

  • The objective of this study was to analyze the two contrary effects of usage habits on the acceptance of a new IT. The one is a positive one which may be caused by expertise from the repetitive usages of a current system while the other is a negative one which would be due to lock-in. For this purpose, this study suggested three hypotheses which account for not only the negative effect of the habit in current system on the intention of using a new system but also the positive moderation effects on both relationships of perceived usefulness and perceived ease of use with the intention of a new system. For the empirical tests of the hypotheses, this study surveyed acceptance of Google Docs for the users who have a habitual used word processor. The analysis by partial least square approach showed that the hypotheses were statistically supported.

  • The purpose of this study was to examine the impacts of educational theater on 5-years-old children, and more specifically, to find out whether the effects of the theater on children's peer acceptance and self-esteem are different by peer social statuses, that are, popular, average, and neglected/rejected Fifty seven children participated in this study and were evaluated with the Sociometric Test (Coie & Dodge, 1983). The experimental subgroup (N=28) participated in the programmed educational theater for 9 sessions. The dependent variables were measured by the peer acceptance items of Sociometric Test as well as the Self-Perception Profile based on SPPC (Halter, 1985), and the same tests were administered twice, before and after the experiment. Covariance analyses showed significant differences between experimental and control groups, for the children in the neglected/rejected category, in peer acceptance and social acceptance dimension of self-esteem. Global self-worth among children of popular and average categories, and total self-esteem among children of average category were also improved by the theater program. These results imply that educational theater programs can be used effectively to promote young children's social adjustment.
