This study was conducted to find out the factors affecting the stages of behavioral change about GMO(n=202 university students). 52.0% of the respondents had no experience in GMO education, the stages of pre-contemplation and contemplation were 35.6% and 29.7%, respectively. Experience and awareness on GMO were the highest at 86.6% and 51.5%, respectively, and 55% of the respondents did not know about the implementation of the labeling system. Positive and negative perceptions on GMO score were 3.41 and 3.22, respectively. The need for the full labeling system of GM foods was 56.4%, the intention not to pay when the price rises due to the system was 70.8%. Regression analysis of factors affecting the stages of behavioral change showed health interest(t=2.10, p<0.05), educational experience(t=2.81, p<0.01), knowledge score(t=2.260, p<0.05), and negative perception(t=2.13, p<0.05). The results of this study suggest that in order to increase the stage of behavioral change in GMO, it is necessary to raise interest in health and knowledge and have the correct perception through GMO education

The purpose of this study is to clarify the effect of plant growth regulator "Uniconazole-P" on the control of growth and seed producrtion of pasture plants under grown in sward conditions. Four species examined were orchard grass, timothy, red clover and alfalfa. Uniconazole-P concentrations were control(0), 20ppm and 40ppm, and foliar sprayed on canopy structures at the floral differentiation stages of grasses and at the begining of flowering stages of legumes, respectively. 1. Yield components and seed yield components of grasses and legumes were responded differently between Uniconazole-P concentrations, species and the stages of growth. 2. At early heading stages, the plant length and culm length of grasses were reduced by Uniconazole-P treatments. On the contrary, the dry weight of ears per area and chlorophyll concentrations were increased by Uniconazole-P treatments. 3. At seed ripening stages, the number of ears, dry weight of a tiller, dry weight of a ear, dry weight of ears per area and dry weight of seeds in orchardgrass, and the number of ears, dry weight of a ear, dry weight of ears per area, dry weight of seeds and harvest index in timothy were increased by Uniconazole-P treatments. 4. At early flowering stages, the plant length and total length of internodes were reduced by Uniconazole-P treatments. On the contrary, total length of branches and chlorophyll concentrations of red clover and alfalfa were increased by Uniconazole-P treatments. Particularly, the number of inflorescences and dry weight of inflorescences of red clover was increased greatly by Uniconazole-P treatments. 5. At seed ripening stages, the plant length of both of legumes were reduced by Uniconazole-P treatments. On the contrary, the dry weight of a inflorescence, dry weight of inflorescences per area, dry weight of seeds and harvest index of alfalfa was increased by Uniconazole-P treatments. 6. Seed production of grasses by Uniconazole-P treatments can be explained as following processes at each stage of growth. 1) reduced in plant length and culm lengths at early heading stages, 2) increased in number of ears and dry weight of a ear at both of stages, and 3) increased in dry weight of ears per area, dry weight of seeds and harvest index at seed ripening stages. 7. Seed production of legumes by Uniconazole-P treatments can be explained as following processes at each stage of growth. 1) reduced in plant length and total length of internodes and increased in number of branches and total length of branches at early flowering stages, 2) increased in number of inflorescences and dry weight of inflorescences at both of stages, and 3) increased in dry weight of seeds and harvest index at seed ripening stages.

The annual changes in testis weight and diameter of seminiferous tubules, and the seminiferous epithelium cycle of Tamias sibiricus were studied by light microscope. Testis weight and diameter of seminiferous tubule are significantly increased from January to July, and decreased rapidly to the size from August to December. Spermatogenesis occurs from January to July, and spermatocytogenesis are produced from August to December. The cycle of the seminiferous epithelium was divided into 12 stages during the development of spermatids as a changes of the nucleus and acrosomal structure, presence and/or absence of residual body, appearance and/or absence of sperm tail and meiotic figure and spermiation. The dark type spermatogonia (Ad) are appeared in all stages (I ~ XII), and the spermatids of step 10 are observed at I, II, X and XII stages. The spermatids of step 11 are appeared in III and IV stages, only the step 12 spermatid observed in V stage.

TQM is a kind of generic strategy. Especially it is a competitive strategy which is concerned with the determination of competitive advantages. Strategic a, pp.oach is very important for the successful implementation of TQM. Unfitness between the company's strategy and the TQM program has been a major barrier preventing the effective implementation. In spite of its importance, little is known for TQM's strategic characteristics. TQM's strategic characteristics are different by its evolution stages. Therefore the generic strategic types that TQM seeks can be changed while TQM programs are progressing over its stages. This paper identifies the intended strategic type of TQM by its stages, which will greatly help to prepare the good implementation program of TQM.

Distribution of farm produce in Korea is known to be inefficient due to the numerous stages that exist in the distribution channel. This has resulted in dissatisfaction for both farmer and consuers; farmers sell their produce at low prices to middlemen while consumers pay high prices for them because of price increases that occur in the distribution chain. We apply Spengler's theory of double marginalization to show that price increases are inevitable as the length of the farm distribution chain increases. We then show that the negative effects of double marginalization can be contained by setting up a physical distribution center. The physical distribution center effectively reduces the stages in the distribution from 5 or 6 stages to 3 or 4 stages. We also lay out the design and major characteristics of the distribution center, as well as the expected cost savings.

The safety accidents of domestic construction happened more than other industries is performed only under the construction stage. In the foreign countries, however, owners and designers play an important role on safety in an early stage. Therefore, numerous studies were carried out by getting rid of accident risks and institutionalizing prevention activities in an construction stages. Accordingly, this study have performed to deduce the pivotal point of safety management items classified by the subject suitable for construction by introducing of safety conception of domestic and international design and suggested the improvement methods of safety management plans of the planning design stage so as to perform more efficient safety management.

The purpose of this study was to reveal controversial issues on Stages of Concern(SoC), which is one of the dimensions of Concerns Based Adoption Model(CBAM). To achieve the purpose, documental analysis was employed. The theoretical framework to analyze literature consisted of three categories including stages, measurements, and applications. Based on the framework, controversial issues on SoC were discussed regarding arguments of CBAM developers and critics. The researchers of this study suggested their own opinions on the issues after thorough examination of CBAM developer's arguments and oppositions against them. Finally, suggestions for further studies on issues of SoC and studies measuring SoC were made.
