본 논문에서는 감옥과 타워의 서로 다른 공간에 있는 두 플레이어가 무전기를 통해 협력하여 퍼즐을 푸는 2인용 퍼즐 탈출 게임을 제안한다. 다양한 경험을 제공하기 위해서, 제안하는 게 임은 염색약 퍼즐, 동물 퍼즐, 레버 퍼즐, 체스판 퍼즐, 독수리 석상 퍼즐, 점프맵 퍼즐, 미로 맵 퍼즐로 구성된다. 제안하는 게임에서는 퍼즐 힌트를 찾는 플레이어와 그 힌트를 바탕으로 퍼즐을 푸는 플레이어가 서로 협력하며, 퍼즐에 따라 플레이어의 역할은 바뀔 수 있다. 또한, 도전 욕구를 자극하기 위해서, 제안하는 게임은 평균 2분 이내로 풀 수 있는 쉬운 퍼즐부터, 평균 16분 내외 걸리는 어려운 퍼즐까지 다양한 퍼즐로 구성된다. 게임이 재미있으면 몰입하 게 되는데, 제안하는 게임은 평균 1시간 내외가 소요됨에도 불구하고 대부분의 플레이어가 포 기하지 않고 끝까지 플레이하는 실험 결과를 보인다.

Paradental cysts characteristically develop adjacent to the cervical margin on the lateral aspect of a tooth root and result from inflammatory processes within the periodontal pocket. Standard management usually involves cyst enucleation while striving to retain the affected tooth. Recurrence rates are infrequent following complete removal of the lesion. However, intentional replantation becomes necessary in cases with anatomical constraints or accessibility issues. We present the case of a 13-year-old female patient exhibiting delayed eruption of the mandibular left second molar, attributed to a cystic lesion located on the lingual-coronal aspect of the tooth.

Orthokeratinized odontogenic cysts are developmental cysts that occur in the jaw that account for approximately 7%–17% of all cysts in the jaws. Studies have shown that malignant transformation of odontogenic cysts most often occurs in inflammatory cysts, such as periapical cysts, but malignant transformation of orthokeratinized odontogenic cysts has also been reported. In this report, we present an uncommon case of squamous cell carcinoma arising from an orthokeratinized odontogenic cyst.

An in vtro nucellar polyembryo propagation method was established with mature seed of the Citrus junos Sieb. 7-8 nucellar polyembryos per seed were induced on MS basal medium without plant growth regulators. The polyembryos developed to complete plantlets on teatment with IBA. These shoots grew further in MS medium without plant growth regulators. Rooting of shoots occurred on MS medium supplemented with IBA. These plantlets were successfully transplanted to small plastic pot containing soil mixture. Somatic embryos were induced from nucellar polyembryo and maturation occurred spontaneously from proliferating cultures on MS medium without growth regulators. Random Amplified Polymorphic DNA (RAPD) marker analysis of in vitro and in vivo grown junos orange showed identical polymorphism indicative of their genetic stability. The RAPD polymorphism produced revealed same banding pattern in each regenerant. Hence, propagaton of junos orange by nucellalr polyembryos was efficient and produced in genetically stable plants under in vitro conditions.
