This paper tried to understand the effects of alcohol-reducing program on drinkings behaviour of workers on works under 5 employees. For these, this paper understood a change of drinkings custom and degree of alcohol-reducing strategy practice by enforcement of alcohol reducing program over 7 times during 3 months Reaults from analyses are as follows 1) A health problems related to drinkings were a chronic fatigue and indigestion, 15.5% was over 5 items among items related to liver disease. 2) The subjector of investigation all was involved over 2 items among items that a drinking custom must be collecred. 3) The change of drinkings custom between before and after on enforcement of alcohol reducing program showed a effective difference. 4) For a degree of the alcohol-reducing strategy practice, "reducing drinkings days" was 82.9%. "bearing drinkings impulse" 70.7%, "exchanging drinkings custom" 56.1%, "avoiding drinkings friends" 51.2%, Yet, "avoiding drinking place" and "preparing leisure activity to exchange drinkings" showed a low practice ratio. 5) For correlation between drinkings drinkings behaviour and degree of alcohol-reducing strategy practice, the more drinkings times before program paticipatance the higher alcohol-reducing strategy practice, alcohol dependency and drinkings times, alcohol-reducing strategy and drinkings times, befere drinking custom had an effective negative corelation, after drinkings custom and alcohol-reducing strategy a strong effective positive corelation. 6) workers writing drinkings paper decreased drinkings times. Implications from results are as follows The alcohol-reducing program is necessary to works under 5 employees, and needs to he operated continously. Especially, in works under 5 emplyees, the alcohol-reducing programt needs to be operated by firm or government.

The study was carried out to investigate the variations in the fibroin hydrolysis of leading silkworm varieties in Korea, and the relationship between the fibroin hydrolysis of the silkworm varieties with some characteristics and silk morphological property. The results obtained are summarized as follows: 1) The fibroin hydrolyzing ratio of both parent silkworm cocoons was reduced in the F$_1$hybrids. 2) A positive corelation (r=＋0.86) was approved between the mid-parent value and the F$_1$hybrid in the fibroin hydrolysis. 3) It was disclosed that the fibroin hydrolyzing ratio of Jam 103${\times}$Jam 104 was the lowest among the leading silkworm F$_1$hybrids. 4) The fibroin hydrolysis was affected by the silk morphological property, showing a positive corelation between the size of cocoon filament and the fibroin hydrolyzing ratio. 5) It was thought that the determination of the fibroin hydrolyzing ratio was useful as a marker for the selection of its related economical characters in silkworm breeding, because the fibroin hydrolysis of parents silkworm cocoons was heritable in their F$_1$hybrids.

We studied to compare the fractionation patterns of Ni, Cu, Zn in Jeju volcanic ash soils and to elucidate the uptakes of them by Pakchoi(Brassica campestris var. chinensis). Fractionation patterns of soils by sequential extraction method were different and make to distinguish from various soil types. In Pakchoi, the transfer rates of Ni, Cu, Zn from root to shoot were also different by metal types. There are low corelation between fractional contents in soil and contents in plants of trace elements except for exchangeable Zn. It is needed to develop novel methods for the assessment soil Ni in relation to plant uptake because of poor corelation.

We studied what kind of science-contents problems can also give information on one's creativity for use in the selection of scientifically gifted. 383 7th and 8th graders as subjects, we first analyzed the corelation between the results of creative thinking, scientific attitude, science inquiry, logical thinking and the scientific creativity problem solving skill test. The corelation analysis indicated that science inquiry test could represent other tests except TTCT. We then tested 532 6th graders with TTCT and science inquiry tests concomitantly with the contents- related problems made in such types as naming 20 scientists, writing about a scientist, imagination to overcome a problem, understanding of theory and application and understanding of science laws and application. The results indicated that writing and imagination were most efficient in assessing both the contents and the creativity.

This study aimed to design and apply the technological pedagogical and content knowledge(TPACK) model to pre-service education program, and to analyze its results for attending student's questionnaire. At first, a lecture that designed to elevate one's technological knowledge was studied and implemented. To perform this study, TPACK survey instruments were distributed to pre-service teacher group A who took the designed lecture and group B who took ordinary ICT literacy lecture. The results showed that TK, TCK, TPK, and TPACK improved significantly in group A, and significant positive corelation shows among 7 subcategories of TPACK. Based on the result of this study, we suggested that pre-service teacher education should consider the combination of pre-service education program and technology knowledge in TPACK model.

This paper introduces a novel approach for automated mapping of a map feature that is vinyl green house in high spatial resolution imagery Some map features have their unique spatial patterns. These patterns are normally detected in high spatial resolution remotely sensed data by human recognition system. When spatial patterns can be applied to map feature identification, it will improve image classification accuracy and will be contributed a lot to feature identification. In this study, an automated feature identification approach using spatial aucorrelation is developed, specifically for the vinyl green house that has distinctive spatial pattern in its array. The algorithm aimed to develop the method without any human intervention such as digitizing. The method can investigate the characteristics of repeated spatial pattern of vinyl green house. The repeated spatial pattern comes from the orderly array of vinyl green house. For this, object-based approaches are essential because the pattern is recognized when the shapes that are consists of the groups of pixels are involved. The experimental result shows very effective vinyl house extraction. The targeted three vinyl green houses were exactly identified in the IKONOS image for a part of Jeju area.
