The enrichment triad model(Renzulli, 1977) which was originally developed for teaching and learning of gifted and talented children consists of three types of enrichment activities. Type Ⅰ enrichment activities build knowledge for later use in 'gifted behaviors', and type Ⅱ enrichment activities focus on the 'how-to skills,' attitudes and values the student must develop to become and effective investigator, problem solver and producer. Type Ⅲ enrichment activities, the pursuit of real problems and realization of gifted behavior, are the fundamental goal for this model. In this study we developed enrichment activities for high school earth science class. We could summarize enrichment activities as follows: In studying the fossil section, after reporting their research activities on fossil data, students can understand the fossil theory through questioning and answering their homeworks. They can enhance their interest and curiosity by watching the movie 'Jurassic Part'(type Ⅰ enrichment activities). After making replica of fossil samples(type Ⅱ), they can write their research reports or articles concerning fossils(type Ⅲ). Students can extend their knowledge about fossils through these types of enrichment activities. In studying weather map section, after collecting newspaper clippings or searching internet, students present their knowledge about weather and weather maps(type Ⅰ enrichment activities). Learning how to make weather maps and investigating how to analyze them, student can extend their knowledge(type Ⅱ). Through these activities, students can apply their knowledge to everyday life experience(type Ⅲ). The third program is 'igneous rock' section. Students investigate the fossil formation in Korea(type Ⅰ enrichment activities). They can understand the principle of volcanic activities through experiment of volcano eruption model type Ⅱ. Through drawing pictures, writing assignment of experiment activities and playing the role play of igneous rocks, teachers can help students to acquire cause or interest to study the igneous rocks(type Ⅲ). In conclusion, within a classroom instruction teachers would be utilizing all three types of activities, moving from one to the other as class, and individual needs, demand. By selecting what students want to do and making them to produce results of their activities, we are expecting that teachers can cultivate creative thinking and enhance problem solving ability of students.

Gastritis cystica profunda (GCP) is a disease characterized by hyperplastic and significant extension of cystic dilatation of the gastric mucous glands, which results in a cystic lesion in gastric submucosa. It often occurs on the part of gastroenterostomy, but can be found in the stomach without any previous surgery. GCP has variable gross finding including solitary polyps, diffuse ones, submucosal tumors, and rare giant gastric mucosal fold. It is difficult to tell GCP from a cancerous lesion by gross finding that the disease demands a necessary tissue biopsy, though GCP is commonly showed as a benign in the progress. We report a case of GCP in polypoid types diagnosed by endoscopic polypectomy.

Gastric angiodysplasia is vascular ectasia in mucosa and submucosa of the gastric wall. It is an uncommon cause of upper gastrointesinal hemorrhage that may occur in the stomach or duodenum. There are many kinds of endoscopic treatments, such as argon plasma coagulation, electrocoagulation, heat probe, and submucosal injection of hypertonic saline mixed with epinephrine for gastric angiodysplasia. However, these treatment methods are associated with high rate of rebleeding. In order to avoid the recurrence, endoscopic band ligation has recently been used as an alternative method for endoscopic treatment of gastric angiodysplasia. We encountered a case of gastric angiodysplasia that presented with overt bleeding and anemia, and was successfully treated with endoscopic band ligation.

It is a quite quality concerning to control temperature of single crystalline it does when you get most of heat treating products. It is also important control temperature when you make the Al203(single crystalline) used to jewels, glass of watches, heat resistant transparent glasses. Thus, it is a ma, to get the proper temperature in accordance with the time process while making mixture of oxygen and hydrogen to have the right temperature. In we will study of electrical valve positioning system for the gas mixture to im quality of products.

Insects have a great potential to be used as feedstocks for biodiesel production due to their intrinsic high lipid contents. In particular, biodiesel production from black soldier fly larvae (BSFL) is promising because of its advantages in engineering aspects such as a rapid proliferation, more lipid storage due to long-development time in larva stage, self-separation from organic waste. In this study, biodiesel was synthesized through (trans)esterification of BSFL grown on food waste to achieve both biofuel production from organic waste materials. In addition, all fuel properties of the biodiesel were examined to evaluate its feasibility as a potential transportation fuel in Korea. The highest yield of biodiesel obtained in this study was 86.51%. All the parameters of biodiesel produced from BSFL satisfied the Korea fuel standard (KS M 2965) except oxidation stability. The quality criterion of oxidation stability met the fuel standard with an addition of small quantity of tert-butylhydroquinone.
