The purpose of this study is to figure out gifted elementary science students' improvement in performing open inquiry after peer review. In this study, gifted fifth-grade students performed open inquiry and review of each other as peers after the inquiry. Students' inquiries were evaluated and the influences of the feedback from the peer reviews were analyzed in relation to the inquiry performances. As a result of this study, three key points were discovered: First, the evaluation score increased with frequent feedback or long discussions. On the other hand, with less feedback, the evaluation score didn't rise. Second, there were three types of improvement in inquiry related to peer review: No. 1 was improvement after feedback given by themselves. No. 2 was reflection of feedback given to other groups. As a last type, No. 3 was that the students learned from other groups' presentation without any feedback and improved their inquiry. Third, there were five kinds of giving feedback; (1) feedback understanding the inquiry correctly, (2) insufficiency of peer's inquiry without deep thought. (3) on the usefulness of the inquiry, (4) on the scientific and logic validity through critical thinking, and (5) how to develop the inquiry. In these kinds of feedback, the fourth kind of feedback (4) occurred most frequently but the fifth (5) occurred rarely. It means peer review helps students develop their critical thinking ability and teachers should encourage students to give peers feedback of the fifth kind.

Objectives: Frozen shoulder (FS) is one of the most challenging shoulder disorders for patients and clinicians. Its symptoms mainly include any combination of stiffness, nocturnal pain, and limitation of active and passive glenohumeral joint movement. Conventional treatment options for FS are physical therapy, nonsteroidal anti-inflammatory drugs, injection therapy, and arthroscopic capsular release, but adverse and limited effects continue to present problems. As a result, pharmacoacupuncture (PA) is getting attention as an alternative therapy for patients with FS. PA is a new form of acupuncture treatment in traditional Korean medicine (TKM) that is mainly used for musculoskeletal diseases. It has similarity and specificity compared to corticosteroid injection and hydrodilatation, making it a potential alternative injection therapy for FS. However, no systematic reviews investigating the utilization of PA for FS have been published. Therefore, this review aims to standardize the clinical use of PA for FS and validate its therapeutic effect. Methods: The protocol was registered in Prospero (CRD42023445708) on 18 July 2023. Until Aug. 31, 2023, seven electronic databases will be searched for randomized controlled trials of PA for FS. Authors will be contacted, and manual searches will also be performed. Two reviewers will independently screen and collect data from retrieved articles according to predefined criteria. The primary outcome will be pain intensity, and secondary outcomes will be effective rate, Constant-Murley Score, Shoulder Pain and Disability Index, range of motion, quality of life, and adverse events. Bias and quality of the included trials will be assessed using the Cochrane handbook's risk-of-bias tool for randomized trials. Meta analyses will be conducted using Review Manager V.5.3 software. GRADE will be used to evaluate the level of evidence for each outcome. Results: This systematic review and meta-analysis will be conducted following PRISMA statement. The results will be published in a peer-reviewed journal. Conclusion: This review will provide scientific evidence to support health insurance policy as well as the standardization of PA in clinical practice.

Most cases of plasma-cell granuloma occur in adult skeleton system. They usually present as a single lesion, but multiple lesions are not uncommon. Roentgenographically, the lesions are lytic, sclerotic or mixed, but in the majority there is some degree of sclerosis. No specific etiologic agent is known, but it is postulated that the reaction may be associated with a variety of organisms of low-grade virulence. Certain organisms have long been known to produce predominantly plasmacytic infiltrate, notably spirochetes, mycobacteria and some exotic viruses. It is most important, however, that this entity, plasma-cell granuloma, be distinguished from multiple myeloma so those potentially life-threatening chemotherapeutic agents are not prescribed. Histologically, aggregates of chronic inflammatory cells are intermingled with the meets of plasma cells, and note the markedly thickened bone trabeculae in surrounding bone. We experienced a case of plasma-cell granuloma of right 7th. rib, occurring in 32 year old male and reported it with review of literatures.

Objectives : The purpose of this study is to search for more effective methods of diagnosis and treatment of Fracture. Methods : Literature review on Fracture in view of oriental and western medicine. Conclusions : Fracture is classified by anatomical location, grade, shape of line, displacement and cause. The symptom of Fracture is pain, tenderness, deformity, attitude, abnormal mobility, crepitus, neurovascular injury. Fracture is not the same in Healing process by location. The age, endocrine system, chronic debilitating disease, stabilization is effect on healing period and process. Treatment of Fracture is classified emergency care, definite treatment and rehabilitation.

The purpose of this study was to examine the instructional effect of problem-based learning on creative problem-solving skills and academic achievement in elementary science classes. Based on the literature review, six stages for problem-based learning were applied: Orientation, Presenting problems and the process of learning, preliminary problem solving, problem solving, sharing results, and wrapping up/evaluating. The subjects were 74 students in two six-grade classes in Gyeonggi province. As a result, the following findings were given: First, the students who were engaged in problem-based learning showed better progress in creative problem-solving skills. Second, science academic achievement of experimental group were better than traditional group. Educational implications were discussed.

Cystadenocarcinoma of salivary gland is an rare, slow-growing, low-grade malignant neoplasm characterized by cysts and papillary endocystic projections. Major locations of this tumor are parotid glands, and minor salivary glands, while occurrence in submandibular gland is extremely rare. Only few cases have been reported in the literatures. Cystadenicarcinoma behaves in an indolent manner and recurrence is rarely occured, surgical complete excision is considered treatment of choice. We experienced a case of cystadenocarcinoma arising from submandibular gland, so we report this case with a review of literature.

Pleural mesothelioma is the tumor of the cell of mesodermal origin lining the pleura. It is relatively uncommon tumor and its localized form is much rarer than diffuse form. Authors experienced a localized mesothelioma in a patient who was 44 year old male worker at copper plumbing field for 20 years, and admitted due to incidentally found abnormal chest X-ray. Exploratory thoracotomy was done and a 23 x 16 x 8 cm sized solitary mass was resected with adherent right middle lobe. Low grade malignancy of the pleural mesothelioma was confirmed by the pathology. We report the case with a literature review.

Metastasizing mixed tumors [MMT] of salivary glands are inexplicably metastasize maintaining benign histology. There is no pathologic and flow cytometric analysis criteria to predict the metastasis. MMT is known to metastasize by local implantation, vascular and lymphatic embolization after multiple surgery to local recurrences of primary tumor. However, multiple metastasis including cranium and spine occurred even without surgery to the primary tumor in this case. No pathological evidence of malignancy could be found in both primary and metastatic tumor. MMT is considered as an low grade malignancy based on clinical behavior rather than histologic evidence, such as low mortality rate, long delay of metastasis after primary lesion. Cranial metastasis is also extremely rare and only two cases have been reported. We report this unusual case with a literature review.

Primary intraosseous meningioma is a rare tumor, and atypical pathologic components both osteolytic lesion and dura and soft tissue invasion is extremely rare. A 65-year-old woman presented with a 5-month history of a soft mass on the right frontal area. MR imaging revealed a 4 cm sized, multilobulated, strongly-enhancing lesion on the right frontal bone, and CT showed a destructive skull lesion. The mass was adhered tightly to the scalp and dura mater, and it extended to some part of the outer and inner dural layers without brain invasion. The extradural mass and soft tissue mass were totally removed simultaneously and we reconstructed the calvarial defect with artificial bone material. The pathological study revealed an atypical meningioma as World Health Organization grade II. Six months after the operation, brain MR imaging showed that not found recurrence in both cranial and spinal lesion. Here, we report a case of primary osteolytic intraosseous atypical meningioma with soft tissue and dural invasion.

In case of neoplasm claims, it is important to make a decision of differentiating malignant and benign. In Korean insurance market, there are many insurance products that cover cancer. In the insurance claims adjustment, differentiation between malignant and benign is according to histologic findings. However there are many neoplasms of bad clinical course in spite of benign histopathologic classification. In this article; astrocytoma, thymoma, gastrointestinal stromal tumor, colonic intramucosal carcinoma, gastric high grade adenoma/dysplasia, carcinoid tumor, MALT lymphoma, revision of Korean Classification of Disease-6th edition, and bladder tumors are reviewed in terms of differentiation between malignant and benign in the insurance claims. It may be helpful for claims staff to review important neoplasms in terms of differentiation between malignant and benign.
