Running title: A plunging ranula extended into parapharyngeal space Ranulas are lesion of sublingual gland origin, which occur in the floor of the mouth. Most ranulas, whether simple or plunging, are pseudocysts without and epithelial lining and ranulas have higher levels of salivary amylase and protein content. They can be classified into two types based on their extent: simple ranulas, confined to the sublingual space and plunging ranula which extend into adjacent spaces. Plunging ranula requires differential diagnosis with other lesions (neuroma, monomorphic adenoma, hemangioma, lipoma, dermoid cyst, lateral cervical cyst). The patient was diagnosed as plunging ranula. We experienced 17 years old male, visited to our department, who complain Rt. cervical swelling and in MRI view, this lesion involved sublingual, submadibular, parapharyngeal, skull base. We experienced a rare case of plunging ranula, extended into parapharyngeal space. We report the case.

Acute eosinophilic pneumonia (AEP) is characterized by idiopathic febrile illness with short duration, severe hypoxemia, diffuse pulmonary infiltration, and eosinophilia in bronchoalveolar lavage fluid. We experienced two cases of AEP following smoking. They started smoking cigarette 3 weeks prior to admission and presented typical clinical and radiological characteristics of AEP. No cause of AEP was identifiable apart from smoking. One patient had never smoked, and the other was an ex-smoker who started small amount smoking 2 years ago but quitted 1 year ago. Pneumonia-like respiratory symptoms were improved after high-dose systemic steroid applied. After an 8-week cessation of cigarette smoking, one of them has resumed smoking 10∼20 pieces per day again. He did not experience any symptom except flu-like symptoms on the seventh day. Chest radiographs showed no infiltration, and flu-like symptoms subsided without any specific therapy. This suggests that cigarette smoking led to AEP in this patient and tolerance might develop against chronic repeated resumption of smoking cigarettes. We should pay attention to awareness of cigarette smoking-induced AEP, especially among the younger generation who started smoking recently. (Korean J Asthma Allergy Clin Immunol 2007;27:277-282)

남북한(南北韓) 대화(對話)의 국내외적(國內外的) 환경(環境)

The purpose of this paper is to investigate some environmental factors that facilitate contacts and dialogue between South and North Korea. Since the conclusion of the armistice agreement in 1953, the two Koreas have maintained a highly tension-ridden relationship, which has become a major element causing the instability and insecurity within and without the Korean peninsula. Those factors are divided into three catagories : They are psycological, operational and international ones. First, the psycological category refers to the perceptions and attitudes of Koreans toward each of the two divided parts. Second, the operational category includes socio-political and economic factors of South and North Korea, which have contributed to the sustaining of different ideas, systems and policies in each part. Third, the international category mainly concerns the global and regional situations which have something particular to do with the Korean peninsula. In this category, diplo-strategic interests and the power configuration among the four major powers, the United States, the Soviet Union, China(PRC) and Japan are deeply examined with the assumption that those factors exert important influence on the development of South - North Korean dialogue. Despite the July 4 the cornmorn communique in 1972, which both sides agreed that Korean unification must be attempted peacefully as well as indepentently, one`` s perceptions and attitudes toward the other are still conflicting and even antagonistic. The people of both Koreas considerably share enemy-images toward each other. These psycological and perceptual factors have been formed through the Korean War and subsequent development of confrontation and conflicts along the de-militarized zone between the two Koreas, It is certain that these factors are highly disfunctional to the improvement of South and North Korean relations. Meanwhile, some operational factors, demonstrating certain changes in political structures and processes, are expected to have positive influences on the opening of dialogue between the two Koreas. Most important are the over-all processes of democratization which is under way in South Korea, and the generational changes in ruling circles and the adoption of open -door policy in North Korea. But these changes will gradually take place, and have some influences on the improvement of inter- Korean relations. Lastly, current international environments surrounding the Korean peninsula prove to be favorable to the maintenance of a stable relationship and to the conduct of negotiations between the two Koreas. The growing mood of detente among the four major powers and their respective relations with the two Koreas will be certainly conducive to the creation of a stable peace structure in the Korean peninsula, which may in turn contribute to the regional stability in Northeast Asia. Although psycological and perceptual factors remain unchanged, it is assumed that they are also affected by the change in operational and international environments. To sum up, the inter-Korean relations are surely entering into a new era that may facilitate the peaceful solution of the unification problem through contacts and dialogue between both`` sides, What is most necessary is that both Koreas increace their capabilities to adopt themselves to the changing environments, which keeping self-restrained interactions between themselves.

Advances in vitiligo research and therapeutic suggestions

신정현 ( Jeonghyun Shin ) 대한피부과학회 2016 대한피부과학회 학술발표대회집 Vol.68 No.2

Vitiligo is a relatively common skin disease, and is an acquired pigmentary disorder characterized by areas of depigmented skin resulting from loss of epidermal melanocytes. The prevalence of this disease varies from 0.2% to 1% in various global populations without sex predilection. Despite recent studies that have contributed new knowledge about the disease, understanding its pathogenesis remains a major challenge. Although several hypotheses have been proposed, an autoimmune response against melanocytes remains the leading candidate. Accordingly, evidences of genetic defects in immune regulation and melanocytes components are increasingly reported. And oxidative stress as the primary intracellular signal for melanocyte degeneration may be the initial event that leads to the activation of the anti-melanocyte immune responses in patients with genetic predisposition to autoimmunity. Recent advances in the understanding of the pathogenesis of vitiligo suggest new therapeutic options such as Janus kinase inhibitors, activated low-dose cytokines-based therapy, miRNA inhibitor, etc. in the near future.

Hybrid laser welding technology is a good process to reduce a thermal distortion and increase the productivity. However, it requires a high investment and a massive modification of the fabrication line such as a gantry system, milling machine for the edge preparation, high power laser system and weld machine. Therefore the development of an economical laser welding system is a crucial point to apply this system in shipbuilding yard. In this study, a portable hybrid laser welding carriage was developed for I-butt joint without edge milling. It is expected that the carriage type system could reduce investment cost.

신정현(Shin, Jeong Hyun),김선희(Kim, Sun Hee),이홍재(Lee, Hongjae),김범성(Kim, Bum Sung),이돈희(Lee, Don Hee) 한국신재생에너지학회 2010 한국신재생에너지학회 학술대회논문집 Vol.2010 No.06

Nowadays, the crystalline Si Solar cell are expected for economical renewable energy source. The cost of the crystalline Si solar cell are decreasing by improvement of its efficiency and decrease of the cost of the raw Si wafers for Solar cells. This Si wafer based crystalline Si solar cell is the verified technology from several decade of its history. Now, I will introduce one method that can be upgrade the efficiency by using simple and economical method. The name of this method is Rear Side Etching(RSE). The purpose of rear side etching is the elimination of n+ layer of rear side and increase of the flatness. The effects of rear side etching are the improvement of Voc and increase of efficiency by reducement series resistance and forming of uniform BSF. The experimental procedure for rear side etching is very simple. After anti-reflection coating on solar cell wafer, Solar cell wafer is etched by the etching chemical that react with only rear side not front side. This special chemical is no harmful to anti-reflection coating layer. It can only etched rear side of solar cell wafer. We can use etching image by optical microscope, minority carrier life time by WCT 120, SiNx thickness and refractive index by ellipsometer, cell efficiency for the RSE effect measurement. The key point of rear side etching is development of etching process condition that react with only rear side. If we can control this factor, we can achieve increase of solar cell efficiency very economically without new device.
