  • This study investigated the literature about science process skills' evaluation to analyse transition of evaluation objectives before and after a Scholastic Ability Test for College Entrance. In the literature survey the researcher established a 3 dimensional science assessment framework with X axis as science concept, Y axis as science process skills and Z axis as problem context. In order to analysis and compare each items the researcher selected 210 items from the 1st to the 7th trials and 138 items from the 1st to 4th Scholastic Ability Test for College Entrance and sampled 2873 science achievement test items from 10 high schools. In accordance with this taxonomy the researcher analysed and compared science process skills item forms. The following results were drawn : The items were evenly distributed in all the four areas(Earth Science, Biology, Physics and Chemistry) of the science concept domain, but they were heavily concentrated on data analysis and drawing a conclusion in science process domain. In the domain of problem context school context was the majority. In spite of distribution like this the ratio on science process skills measurement items and science achievement test items was increased after the Scholastic Ability Test for College Entrance was given. Also the ratio on item expression type was increased. Item form was almost 5 options selection type in the national level test. Although there were 4 options selection type, 5 options selection type, short answer type, essay type in school level test, rising from 33.1% to 65.5% on 5 options selection type is exhibited. This study showed that the school level item form was better various than the nation level. This point like this is the evidence for the improvement toward the science process skills test and influenced by Scholastic Ability Test for College Entrance. The ratio on the item which joined with the 3 axes had a mean of 99.3% in nation level test and mean 44.9% in school achievement test level. But the ratio in the school achievement test level increased after the Scholastic Ability Test for College Entrance was given. In view of this study we must furthermore study the item types which can evaluate valjdately science process skill's five stage each and evaluation method by the high school students' problem solving patterns and features in scientific inquiry on all science process skills elements.

  • Based on the method of marking the size of children's wear suggested by Korean Agency for Technology and Standards, this study classified the heights of school-aged girls by 10cm. The purpose of this study is to provide foundational material by analyzing and comparing the characteristics of torso types. The author analyzed the height section of 130 to 139.9cm, which the majority of subjects fell into, and concerning the method of research, this study statistically analyzed body sizes and calculated items related to 162 persons' torso types out of the 6th Korean Body Size Data. According to the results, eight factors were extracted, and the total explanatory variate of all the factors was found to be 81.93%. According to the results of cluster analysis with it as an independent variable, three types were drawn. Type 1 (41.4%) was found to be the thickest in the torso and round and severely curved in the sectional form of the circumference item. RegardingType 2 (25.9%), the horizontal size of the torso is similar to that of Type 1: the upper body is long, and the sectional form of the circumference item is oval-shaped. Regarding Type 3 (32.7%), mean values are similar to those of Type 2 overall: the upper body is short, and the body is the most upright. In conclusion, according to the results of analyzing torso types, the types and average values indicate significant differences in the height section of 130~139.9cm. This implies that when making ready-made clothes, it is necessary to come up with the sizes of more detailed items in relation with height. It is expected that the findings of this study will be utilized as basic data when children's wear companies develop prototypes and use grading variances according to the variations of size.

  • Both the importance and process of estimating Nuclear-power plant construction time and cost have increased in significance as energy user costs themselves have become more significant. In estimating construction time, few parameters are more significant than work item production rates and factors significantly affecting the rates. A standardized data collection tool was used to acquire a total of 401 data points from a S Nuclear-power plant project, for selected critical works: form-work, rebar-work, and concrete-pouring. With the data, several hypothesized drivers of the man-hour production rates and crew-day production rates were also analyzed. Findings from this study will enable industry professionals to enhance accuracy of time and cost estimation for nuclear power plant construction.

  • This study examined the construct validity of a Korean translated version of the Gifted Rating Scales-School Form (GRS-S). Data were collected from five elementary schools in a metropolitan area and a midsize town in South Korea. Confirmatory factor analysis results indicated that the original factor structure (6-factor solution) fit the data collected from the teachers. However, the 6-factor solution did not fit the data collected from the parents. Thus, exploratory factor analysis was conducted for the parent data. The results showed that seven factors were extracted, and the factors explained 71.96% of the total variance. Unlike the original factor structure, some items of the academic ability scale were grouped with intellectual ability scale, and a creativity scale item and another academic ability scale item were an independent factor. The study outcomes provide preliminary support for a translated version of the GRS-S with elementary students in Korea. More detailed interpretations and implications of the results are discussed in the study.

  • This exploratory research explores the concept of a digital legacy as a general concept and as a collection of digital possessions with unique characteristics. The results reported in this article are part of a larger study. In Cushing (2013), the author identified the characteristics of a digital possession. In this study, these characteristics of a digital possession were utilized to explore how the characteristics of several digital possessions could form a collection, or a digital legacy. In addition to being explored as a collection of digital possessions, data was collected about the general concept of a digital legacy. In part I of the study, 23 participants from three age groups were interviewed about their general concept of a digital legacy. Five general characteristics describing a digital legacy were identified. In part II of the study, interview data from Cushing (2013) was used to create statements describing digital possessions. The statements were classified utilizing the archival concept of primary and secondary values, as well as the consumer behavior concepts of self extension to possessions and possession attachment. Primary value refers to the purpose for which the item was created, while secondary value refers to an additional value that the participants can perceive the item to hold, such as a perception that an item can represent one's identity. Using standard Q method procedure, 48 participants were directed to rank their agreement with 60 statements (written on cards), along a distribution of -5 to +5, according to the characteristics of the digital possession they would most like to maintain for a digital legacy. The ranked statements were analyzed using Q factor analysis, in order to perceive the most common statements associated with maintaining digital possessions for a digital legacy. Q method results suggested that most individuals described the digital possessions they wanted to maintain for a digital legacy using various combinations of characteristics associated with primary and secondary values. This suggests that while some participants will respond to personal archiving based on the concept of preserving identity (a perceived secondary value), this will not appeal to everyone. Information professional could consider this difference in appeal when marketing personal archiving assistance to patrons.
