Hypothyroidism was induced in three age groups (8 months, 1 year and 2 years) of Black Bengal goats by administering thiourea subcutaneously for 30 days. From fourth day onwards the animals were observed to be in hypothyroid state. For 8 months age group, a control group of similar age was taken. For the 1 year and 2 years age groups there was no control group but the values obtained on the pre-treatment day were considered as control values. For confirming the establishment of hypothyroidism, peripheral plasma triiodothyronine $(T_3)$ and thyroxine $(T_4)$ were estimated in all the animals before and during the treatment period by radioimunoassay. In the thiourea treated 8 months age group the $T_3$ and $T_4$ levels were significantly (p<0.001) lower than those in the control group during the treatment period. In all the thiourea treated groups the $T_3$ and $T_4$ levels observed during the treatment period were significantly (p<0.01) lower than the pre-treatment levels. A nonsignificant loss in the body weight was observed in all the thiourea treated groups whereas there was a significant growth in the control group of animals. The study indicates that hypothyroidism has a negative effect on growth in goats.

Purpose: The Quality and Safety Education for Nurses [QSEN] initiative group has identified six competencies (patient-centered care, teamwork and collaboration, evidence-based practice, quality improvement, safety, and informatics) for pre-licensure nursing education along with related knowledge, skills, and attitudes for each competency. The purpose of this article is to illustrate a teaching strategy that uses films to demonstrate the QSEN competencies in undergraduate nursing students. Method: A literature review was conducted to define QSEN competencies, and six feature-length commercial movies were selected through a systematic process. We provided film titles and their synopses that can be useful in teaching the QSEN six competencies to undergraduate nursing students. Results: Patch Adams for patient-centered care, Wit for teamwork and collaboration, Lorenzo's Oil for evidence-based practice, Am$\acute{e}$lie for quality improvement, Blindness and The Island for informatics can be applied in nursing classroom practices. Conclusion: Establishing the connection between QSEN competencies and cinenurducation is novel, yet it would provide a unique opportunity for nurse educators seeking to overcome the challenge of better preparing future nurses. In future studies, additional films should be considered to enhance nursing educational strategies.

This paper presents a cooperation strategy between a human operator and autonomous robots for an interactive robot soccer game, The interactive robot soccer game has been developed to allow humans to join into the game dynamically and reinforce entertainment characteristics. In order to make these games more interesting, a cooperation strategy between humans and autonomous robots on a team is very important. Strategies can be pre-programmed or learned by robots themselves with learning or evolving algorithms. Since the robot soccer system is hard to model and its environment changes dynamically, it is very difficult to pre-program cooperation strategies between robot agents. Q-learning - one of the most representative reinforcement learning methods - is shown to be effective for solving problems dynamically without explicit knowledge of the system. Therefore, in our research, a Q-learning based learning method has been utilized. Prior to utilizing Q-teaming, state variables describing the game situation and actions' sets of robots have been defined. After the learning process, the human operator could play the game more easily. To evaluate the usefulness of the proposed strategy, some simulations and games have been carried out.

A study on the dietary habit and the food perference of Pre-school Children was made in order to identify the state of their dietary life and provide the data of dietetic education which can help the children to live a desirable food life, by analysing the present dietry life into the dietry habits, food preference, the actual condition of nutrition intake and table manners. 1. The Diet Habits. Both boys and girls were fond of dinner best and tended to neglect breakfast and lunch. 64.2% of the total children took meals regularly. 2. Food Preference. The most favorite food was beef, ham, Dupoo (beancurd), squid, ice-cream, bananas, watermelon, sweet potatoes, corn, Ingeolmi (cake form glutinous rice), doughnuts, JJajangmyon (Chinese noodles), Coke, fried chicken. 3. The Actual Conditions of Nutrition Intake. The frequency of intake of meat and its processed food was the lowest and that of fishes, shellfishes, fats and vegetables was low, too. 4. Table manners and Sanitary Conditions. The average mark of table manners and sanitary conditions is 12.49${\pm}$2.65. The children didn't practice well in the following points; talking at table, beginning to eat after the beginning of elder person's, brushing their teeth after taking meals, keeping a straight posture.

Two enhancements to a recently developed plastic-damage-contact model for concrete are presented. The model itself, which uses planes of degradation that can undergo damage and separation but that can regain contact according to a contact law, is described. The first enhancement is a new damage evolution function which provides a completely smooth transition from the undamaged to the damaged state and from pre-peak to post-peak regions. The second is an improved contact function that governs the potential degree of contact with increasing opening on a crack plane. The use of a damage evolution function with a pre-peak has implications for the consistent tangent matrix/stress recovery algorithm developed for the model implementation, and amendments to this algorithm to accommodate the new function are described. A series of unpublished experimental tests on notched specimens undertaken in Cardiff in the mid 1990s are then described. These include notched beam tests as well as prismatic and cylindrical torsion tests. The tests are then considered in three dimensional finite element analyses using the modified Craft model implemented in the finite element program LUSAS. Comparisons between experimental and numerical data show reasonable agreement except that the numerical simulations do not fully describe the latter stages of the softening responses for the torsion examples. Finally, it is concluded that the torsion tests described provide useful benchmark examples for the validation of three-dimensional numerical models for concrete.

So for the quartz-glassy crucible wastes which was used for pulling up silicon-single-crystal ingot have simply reused for refractory raw-materials, or exhausted. This study is concerned on the advanced recycling-technology that is obtained by the proper micro-particle preparation process in order to fabricate fine amorphous silica filler for EMC (Epoxy Molding Compound). Therefore, this paper will deal with the physical, chemical and thermal pre-treatment process for efficient impurity removal and with the proper micro-particle process for producing the amorphous silicafiller. In view of the results, if the chemical, physical and thermal pre-treatment process for efficient elimination of impurity was passed, the purity of wasted fused glassy crucible is almost equal to the its of first anhydrous quartz glass. Thus, it was understood that this wasted fused glassy crucible was sufficient value of recycling, though it was damaged. When the ingot was fabricated, Phase transformation of crystallization by heat treatment (heat hysteresis phenomenon) was not changed. So, it was understood that as fused silica in the amorphous state, as It is, recycling possibility was very high

The 123Te(p,n)123I, 124Te(p,n)124I and 124Te(p,2n)123I reactions, among the many reaction channels opened, are the major reactions under consideration from a diagnostic purpose because reaction residuals as the gamma emitters are used for most radiophamaceutical applications involving radioiodine. Based on the available experimental data, the absorption cross sections and elastic scattering angular distributions of the proton-induced nuclear reaction on Te isotopes below 60 MeV are calculated using the optical model code APMNK. The transmission coefficients of neutron, proton, deuteron, trition and alpha particles are calculated by CUNF code and are fed into the GNASH code. By adjusting level density parameters and the pair correction values of some reaction channels, as well as the composite nucleus state density constants of the pre-equilibrium model, the production cross sections and energy-angle correlated spectra of the secondary light particles, as well as production cross sections and energy distributions of heavy recoils and gamma rays are calculated by the statistical plus pre-equilibrium model code GNASH. The calculated results are analysed and compared with the experimental data taken from the EXFOR. The optimized global optical model parameters give overall agreement with the experimental data over both the entire energy range and all tellurium isotopes.

This formative evaluation study presents a professional development program, "Earth Science Systems for Teachers (ESST)" held in a Midwest State in the United States. This study investigates how a professional development for urban teachers affects the teacher participants' perceptions of using the urban environment for their science teaching and their lesson unit development. The purpose of the program was to help urban teachers create science units using the urban geologic environment and its connection to urban students' everyday lives. The participant teachers' daily journal entries during the program, their lesson plans before and after the program, as well as their teaching reflections were collected as major data source. The teachers' daily journal entries were analyzed qualitatively and their pre-post lessons were analyzed quantitatively using a lesson plan analysis tool, Culturally Relevant Science Teaching Perspectives (CRSTP) was developed by the author. The lesson analysis tool was used to assess teachers' science lesson plans in the perspective of culturally relevant pedagogy and place-based pedagogy. The major findings include: 1) The teacher participants' field experiences in urban geologic sites and urban environments help the teachers to change their perceptions of using the urban environment as a teaching resource and 2) there were significant differences in their pre and post lesson unit scores based on CRSTP (P<. 01). The implications of this study are also discussed.
