One of the biggest changes in the 2015 revised mathematics curriculum is shifting to the second year of middle school in Pythagorean theorem. In this study, the following subjects were studied. First, Pythagoras theorem analyzed the expected problems caused by the shift to the second year middle school. Secondly, we have researched the reconstruction method to solve these problems. The results of this study are as follows. First, there are many different ways to deal with Pythagorean theorem in many countries around the world. In most countries, it was dealt with in 7th grade, but Japan was dealing with 9th grade, and the United States was dealing with 7th, 8th and 9th grade. Second, we derived meaningful implications for the curriculum of Korea from various cases of various countries. The first implication is that the Pythagorean theorem is a content element that can be learned anywhere in the 7th, 8th, and 9th grade. Second, there is one prerequisite before learning Pythagorean theorem, which is learning about the square root. Third, the square roots must be learned before learning Pythagorean theorem. Optimal positions are to be placed in the eighth grade 'rational and cyclic minority' unit. Third, Pythagorean theorem itself is important, but its use is more important. The achievement criteria for the use of Pythagorean theorem should not be erased. In the 9th grade 'Numbers and Calculations' unit, after learning arithmetic calculations including square roots, we propose to reconstruct the square root and the utilization subfields of Pythagorean theorem.

본 연구의 목적은 의학교육에서의 행복과 관련된 교육과정 도입을 탐색하기 위하여 의학전문대학원생들이 행복을 느끼는 활동 및 행복에 대한 개념 인식구조의 사전-사후변화를 분석하였다. 연구대상은 의학전문대학원에 재학 중인 2학년 학생 총 36명이었고, 일상재구성법과 네트워크분석을 사용하였다. 연구결과, 의학전문대학원생들은 먹기/대화하기, 여가활동을 하면서 행복을 많이 경험하고 있는 반면 학습활동을 통한 행복을 느끼는 빈도는 낮게 나타났다. 사전-사후의 행복을 표현하는 단어들은 많은 부분 유사하였고, 사전에는 '경제', 사후에는 '일'이 가장 높은 연결정도중심성을 나타냈다. 행복에 대한 개념의 구조가 1개 그룹에서 자신의 일, 가족의 건강, 삶에 대한 가치, 긍정적인 자아 등의 4개 그룹으로 나누어져 행복에 대한 개념이 피상적인 행복에 대한 개념에서 실제적인 행복에 대한 개념으로 인식이 변화하였다. 따라서 인간의 건강을 다룰 예비의사들이 행복에 대한 개념과 가치 등을 바르게 정립할 수 있도록 행복에 대한 의도적인 교육이 도입되어야 하고, 이를 위해서 행복과 관련된 교육과정이 체계적으로 개발되어야 할 것이다.

As the exiting school facilities become old and unfit for new curriculum, the systematical remodelling process based on its educational and physical functions is required. due to the inadequate maintenance and repairing practices, unnecessary costs are expended. Therefore, this study aims to establish a remodelling decision-making model for improving the educational environment of the existing school facilities. According to the budget system, it proposes the concept of remodelling that includes the activities of extension, reconstruction, repair and improvement. This study classifies the performance evaluation for school facilities as that of safety, durability and educational function, and articulates the assessment standards, methods and elements. In the end, it suggests a rational model for remodelling decision-making that can provide efficient and comprehensive remodelling process, economic and sustainable school development.

The latissimus dorsi myocutaneous flap (LDMF) was initially described at the turn of the century by Tansini et al, and latissimus dorsi myocutaneous free flap (LDMFF) was also first described for the coverage of a chronically infected scalp by Maxwell et al. As a pedicled flap, LDMF has been often used for breast reconstruction and for soft tissue replacement near the shoulder and the lower reaches of the head and neck. LDMFF is a flat and broad soft tissue flap with large-caliber thoracodorsal vessels for microvascular anastomosis. A skin paddle of the LDMFF can be more than $20{\times}40$ cm, so very large defects in the oral cavity and outer facial region can be covered by this LDMFF. Other advantages include consistent vascular anatomy, acceptable donor site morbidity and the ability to perform simultaneous flap harvest with tumor resection. For a better understanding of LDMFF as a routine reconstructive procedure in large defects of the oral cavity and facial legion, anatomical findings must be learned and memorized by young doctors during the special curriculum periods for the Korean national board of oral and maxillofacial surgery. This review article discusses the anatomical basis of LDMFF with Korean language.

A reconstruction following a resection of malignant oral cavity tumors is one of the most difficult problems in recent oral oncology. For a better understanding of oral and maxillofacial reconstructive procedures, basic and advanced microvascular anastomosis techniques must be learned and memorized. The aim of this article was to clarify and define the microvascular anastomosis methods, such as primary closure after an arteriotomy, end to side anastomosis, end to end anastomosis, and side to side anastomosis with an artery and vein. This review article discusses the basic skills regarding microvascular anastomoses with brief schematic diagrams in the Korean language. This article is expected to be helpful, particularly to young doctors in the course of the Korean national board curriculum periods for oral and maxillofacial surgery.

Over the past few years, a large number of perforator flaps have been revised by several microsurgeons in the USA, France, Canada and Japan. A perforator flap is a flap of skin or subcutaneous tissue that is based on the dissection of a perforating vessel, which is a perforator. In short, a perforator is a vessel that has its origin in one of the axial vessels of the human body. By reducing any muscle harvesting and trauma to a minimum, perforator flaps aim to minimize donor site morbidity, and by avoiding the transfer of dennervated muscle, the long-term bulk of the free tissue transfer becomes more predictable. There are a finite number of potential perforator flaps in the body, which are based on the named source arteries. The most commonly used perforator flaps are deep inferior epigastric perforator, superior gluteal artery perforator, thoraco dorsal artery perforator, medial sural artery perforator, and anterolateral thigh perforator flap. For a better understanding of perforators as a routine reconstructive procedure in oral and maxillofacial surgery, the definition with nomenclature, classifications with special characteristics, and review points for their individual applications must be learned and memorized by the young doctors in the course regarding the special curriculum periods for the Korean national board of oral and maxillofacial surgery. Perforator flaps have been known to have many advantages, so this review article summarized their applications to the maxillofacial reconstruction in the Korean language.

The anterolateral thigh flap (ALTF) is a versatile fasciocutaneous or myocutaneous flap, which can be harvested incorporating several skin islands and muscle components. The perforator of the ALTF is usually derived from the descending or transverse branch of the lateral circumflex femoral artery, and these vessels are based mainly on musculocutaneous perforators traversing the vastus lateralis muscle, and also based on the septocutaneous vessels running in between the rectus femoris and vastus lateralis muscle. Despite its usefulness for the oral cavity reconstruction, anatomic variations of these nutrient vessels, such as three main branches of ALTF and its relations with sartorius, vastus lateralis, tensor fasciae latae and rectus femoris muscle, have been reconstructive surgeons to be hesitated for the selection of ALTF. For the better understanding of ALTF as a routine reconstructive procedure in oral and maxillofacial surgery, various anatomical findings must be learned and memorized by young doctors in the course of the special curriculum periods for the Korean national board of oral and maxillofacial surgery. This review article will discuss the vascular anatomy and relavant anatomical variations of ALTF with Korean language.
