The Bronchial stump disruption in bronchopleural fistula with empyema thoracis after pneumonectomy has remained one of the most dreaded complications of thoracic surgery. Management of chronic bronchopleural fistula still poses a therapeutic dilemma in spite of various surgical techniques that have been attempted to control this complication. Only recently, transsternal transpericardial approach for repair of the postpneumonectomy bronchopleural fistula has been utilized in some cases. The patient was a 31 year-old woman who was admitted to our hospital on August 18th, 1989 due to right postpneumonectomy bronchopleural fistula with empyema thoracis for 5 years since she had undergone right pneumonectomy due to pulmonary tuberculosis at E-hospital in 1984. Transsternal transpericardial closure of the fistula was employed and then the thoracic catheter was removed two months later, after the empyema cavity was sterilized by the Clagett method. So, we think this surgical technique is a relatively simple and effective method to the control of chronic postpneumonectomy bronchopleural fistula with empyema thoracis.

A case of squamous cell carcinoma of the thyroid gland associated with esophageal carcinoma is presented A squamous cell carcinoma of the thyroid gland is rare and is prognosis is poor. The histogenesis of squamous cell carcinoma is not clear, but at present, it is believed that most cases arise from the follicular epithelium It is very important to know whether squamous cell carcinoma of the thyroid is primary or secondary. Thus, the possibility of squamous cell carcinoma in the thyroid being the result of a metastasis or extension from a primary tumor in the trachea or esophagus must always be ruled out and intensive evaluation should be required to confirm the diagnosis of this disease. We report a squamous cell carcinoma of the thyroid associated with esophageal cancer with brief review of literature.

Minor salivary gland sialolithiasis (MSGS) is a not uncommon oral mucosal disease. Its clinical appearance may mimic a mucocyst or other benign submucosal overgrowth. Stasis of saliva, which accompanies MSGS, usually results in minor salivary gland inflammation, with a chronic sialadenitis appearance. MSGS typically is a painless lesion but can become painful when the salivary gland parenchyma or excretory duct becomes infected, with or without pus. However, misdiagnosis of this condition is rather common, as the clinical appearance is asymptomatic. The most common location is the upper lip, and MSGS affects males and females, with a slight predilection for males. The sialolith causing MSGS may be obvious during surgical excision, as in the case reported. In other cases, sialolith may be absent or fragmented. Differential diagnosis includes mucocele, swelling due to local irritation like fibroma and diapneusia, chronic abscess of the oral mucosa, and neoplasms either benign (lymphangioma, pleiomorphic adenoma) or malignant. Histopathological examination is needed to establish clinical diagnosis.

Recently, flipped learning is being highlighted especially at the college of engineering because of its self-directed learning which direction matches that of the engineering education system. Although many engineering professors have tended to apply the flipped learning to their classes, they experienced a number of significant problems and challenges in practical implementing. By using TRIZ method as a tool for creative problem solving, that have been developed and applied in many fields ranging from engineering as well as management, this study aims to solve the education dilemma between learning efficiency and learning effectiveness, create a new concept of the flipped learning based on the solutions, and then explore its educational feasibility for successfully adopting it to engineering courses. This study suggests an instructional design for implementing the flipped learning according to the characteristics of engineering classes and then designs a new model of the flipped learning according to that procedure. Also, based on the empirical results in applying a new flipped learning model to the applied mathematics, this paper proposes several guidelines for the successful application of flipped learning in the future.

ICT의 발전은 정부로 하여금 개인 맞춤형 서비스에 초점을 두는 계기를 만들었다. 그러나 이러한 개인 맞춤형 서비스는 시민들의 요구를 충족시키기 위하여 더욱 많은 개인 정보를 요구할 수밖에 없다. 이는 결국 ICT에 의한 역기능 중 하나인 개인 정보 보호 논쟁을 야기하는 딜레마에 봉착하게 한다. 이에 본 연구는 개인 정보 보호 논쟁의 대표적인 사례 중 하나인 NEIS 사례를 활용하여 갈등 당사자의 인식에 대한 분석을 진행하였다. 사례 분석을 위하여 공공갈등 분석에서 원용되는 프레임 분석을 본 연구의 분석틀로 활용하였다. 프레임 분석을 활용하여 찬성 측과 반대 측의 인식을 알아보고, NEIS 사례의 시사점을 도출하였다. 또한 NEIS 사례의 분석 내용을 토대로 향후 정보화 정책 시행과정에서 야기될 수 있는 갈등을 방지하고자 정책적 제언을 제시하였다. 향후 정보화 정책은 정책 당사자의 의견수렴 및 정책 참여를 장려해야 하는 거버넌스 적인 접근을 지향할 필요가 있다.

The security environment surrounding the East Asian seas is rapidly changing due to the naval arms race among coastal states. The arms race is likely to worsen the security dilemma of the countries involved, thus increasing the chances for armed conflicts. It is too early to tell how the contemporary naval arms race in the region will evolve. But, for sure, the level of uncertainty is increasingly becoming high and intense. At the same time, there is emerging a legal warfare or lawfare among the rival countries. In particular, the United States and China have been involved in a serious debate about the nature and scope of the right of innocent passage and freedom of navigation in other countries' maritime zones. In collaboration with its regional allies, the United States has also put normative pressures on China with its excessive claims in the South China Sea. The latest arbitral tribunal case between the Philippines and China illustrates the point. With both arms race and normative competition in play, the future of East Asian maritime security will remain very complex and uncertain.

Composite skull defects in patients with severe head injuries are very challenging to manage. The dilemma when deciding whether to perform a definitive reconstruction is how long to wait for physiological recovery before an intervention complicates the situation. The inability of such patients to tolerate prolonged anesthetic exposure is a driving factor for performing the minimal intervention necessary to facilitate recovery. Herein, we present a case involving the successful immediate reconstructive treatment of a severely head-injured adolescent with a composite scalp defect secondary to trauma. A 14-year-old boy sustained a severe head injury from a motor vehicle accident with a composite scalp defect in the right fronto-parietal region. The frontal lobe was exposed, and the right eye was crushed and devitalized. The patient was deeply unconscious for 3 days, without any significant improvements before reconstructive surgery was proposed due to fear of possible meningitis resulting from the exposure of brain structures. We successfully managed the patient with a fronto-parieto-occipital flap, after which the patient promptly recovered consciousness.

After successful nuclear tests Pakistan launched a more severe surprise attack toward India than before. It is highly possible that North Korea will adopt this Pakistan military strategy if it is armed with nuclear weapons. The North Korean forces armed, with nuclear bombs could make double its war capability through strengthening aggressive force structure and come into effect on blocking reinforcement of the US forces at the initial phase of war time. Therefore we may regard that Pyongyang's nuclear arming is a major one of various factors which increase possibility of waging a conventional warfare or a nuclear war. North Korea's high self-confidence after nuclear arming will heighten tension on the Korean Peninsula via aggressive military threat or terror toward South Korea, and endeavor to accomplish its political purpose via low-intensity conflicts. For instance, nuclear arming of the Pyongyang regime enforces the North Korean forces to invade the Northern Limit Line(NLL), provoke naval battles at the West Sea, and occupy one or two among the Five Islands at the West Sea. In that case, the South Korean forces will be faced with a serious dilemma. In order to recapture the islands, Seoul should be ready for escalating a war. However it is hard to imagine that South Korea fights with North Korea armed with nuclear weapons. This paper concludes that the Pyongyang regime after nuclear arming strongly tends to occupy superiority of military strategy and wage military provocations on the Korean Peninsula.
