Majority of toothache is caused by abnormality of pulpal or periodontal tissues. However, there are numerous nonodontogenic sources that may be responsible for pain felt in the tooth. Nonodontogenic toothache may result from muscle, maxillary sinus, neuropathic, neurovascular, even cardiac and psychogenic problems. Myofascial pain is one of the most common abnormality characterized by palpation of a hard band which acts as the trigger point that causes stiffness and fatigue of the muscle, referral pain in tooth, tension-type headache, and hyperalgesia. Masseter muscle particularly induce referral pain in maxillary and mandibular molars. This case reported the treatment of the pain in right mandibular molar originated from myofascial pain of the right masseter. The pain is improved by general and reversible treatments such as muscle exercise, physical therapy, and medication. Nonodontogenic toothache should undergo proper differential diagnosis in order to avoid unnecessary dental treatments, such as endodontic, periodontic treatment, and tooth extraction, which would fail to alleviate the symptom of the patient.

Toothache is a common complaint in the dental office. Most toothaches have their origin in the pulpal tissues or periodontal structures1). These odontogenic pains are managed well and predictably by dental therapies. One of the most frequent encounters and most confusing phenomena with which the dental diagnostician must deal is the problem of referred pain. The most important step toward proper management of a toothache is to consider that the pain may not be of dental origin. And Patients with orofacial pain, especially those in chronic pain, present a diagnostic and management challenge for the practitioners. There are many structures in the head and neck that can produce heterotopic pains felt in the teeth and other structures. Once referred pain is suspected, the true source of the pain must be located in order to render effective therapy. With increased interest in temporomandibular disorders and orofacial pain, many studies of accurate diagnosis and differential diagnosis about orofacial pain have been established. The purpose of this paper is to present a case for pansinusitis which produced pain referral in teeth and mimicked the symptoms of migraine.

말라리아는 Plasmodium 속 원충으로 인하여 적혈구와 간 세포내에 발병하는 감염병으로, 매년 약 3-5억의 발병과 100만 명 이상의 사망자로 인하여 세계보건기구(WHO)가 선정한 6대 열대병 중에서도 가장 중요한 질환으로 고려되고 있다. 우리나라에서도 법정전염병 제3군으로 지정된 중요한 감염병이다. 국내에서는 지난 2000년 이후 감소 추세를 보이던 국내 말라리아 환자발생(현역 군인 포함)이 2005년 1,324명, 2006년 2,021명, 2007년 2,192명으로 2007년 국내 말라리아 환자는 전년대비 8.5%의 증가를 보이고 있다. 일반적으로, 매개체를 통한 감염병은 생태계 내에서의 상호 작용에 영향을 받기 때문 기후 인자와도 큰 영향을 받는 것으로 알려져 있다. 특히, 모기 매개 질병은 기후의 영향을 크게 받으며, 기온, 강수량, 습도 등의 수문기상 요소가 중요한 영향을 미치며, 그 중에서도 말라리아는 매개체에 의한 전염병 중 가장 중요하게 다루어지는 전염병인 동시에 기후변화에 가장 민감한 질병이다. 이 때문에 말리리아와 기후 인자 및 기후변화를 연관 지으려는 연구가 다수 수행되어 왔으며, 특히 최근에는 습지와 기후 인자와 말라리아의 상관관계를 분석하는 등의 다각적인 분석도 이루어지고 있다. 또한, 최근에 기후변화가 현실적인 문제로서 부각되면서 말라리아의 발생 문제에 대한 연구도 다각적으로 수행되고 있다. 본 연구에서는 기후 인자 및 기후변화와 상관성이 높은 감염병 중에서 국내 발병자 수가 많아서 분석이 용이한 말라리아를 주요한 감염병으로 선정하고, 말라리아의 발생과 기후 인자와의 상관관계를 살펴보고, 이를 바탕으로 기후 인자에 따른 말라리아의 발생을 모의할 수 있는 모형을 구축하고, 실제 적용성을 검증하였다. 이를 위하여 2001년부터 2011년까지의 월간 말라리아 감염병 발생 현황과 전국 기상대의 기후인자를 수집하였다. 말라리아와의 상관 분석을 위해서 포함된 기후인자는 평균기온($^{\circ}C$), 상대습도(%), 강수량(mm)을 이용하여 연관성을 분석하였으며, 이를 회귀 모형화 하였다. 연구결과, 구축된 회귀 모형이 말라리아 발생자료에 대한 설명력이 있는 것으로 나타났다.

This study was performed to decide how to do research and resolve on mental health problems of the people after reunification, which is recognized as ultimately important issue. At first we analyzed the case of Germany. To do so, we reviewed the existing research, which included various issues such as reunification for the Germans, chronological research flow analysis, the issues of mental health, research methods for mental health problems, therapy for mental health problems and so on. And then we sought the ways to connect research for the North Korean defectors and unification era, and suggested the several research orientation and methods for mental health study of the unification period.

Interest of unconventional Oil and Gas, which is produced in a different way, has been increasing due to exhaustion of traditional oil and gas. However production of unconventional Oil and Gas is closely related to its technology level. Accordingly in this research, we can analyze technology level of unconventional Oil and Gas with country/sector/year patent analysis. Through the result of this research, U.S is highest patent application national, patent application in oil sand is increasing. In addition, oil sands-realated patents and shale oil-realated patents applying actively in early 1970's and since the mid-1980's showed a decreasing trend. And patent application in unconventional oil and gas has been increasing due to the rise in the oil price 2000's.

Quantitative analysis of distribution characteristics of soils in Jeju Island was conducted by using geographic information system (GIS) technology. Soil series could be classified 5 groups after cluster analysis with proximity ratios among soil series which mean ratios of boundary lengths of other soils to total boundary length. Classification with proximity only was similar to conventional classification system at detailed soil map although conventional system was made from several criteria such as soil color, altitude and chemical characteristics of soils. Altitudinal sequence of soil series was also suggested from representative altitudes of them which could be found from areal distribution curve along altitudes. The sequence was brown forest soils - black soils - very dark brown soils - dark brown soils from the peak of Halla Mt. to the coast on all sides, which maybe related to pedogenesis process in Jeju Island.

사회적기업, 협동조합, 소셜벤처 등 사회적경제의 부상으로 이들이 전체 경제에서 차지하는 비중이 커지고 있어 북한, 통일 관련 연구에서도 접목이 필요하다. 사회적경제는 북한·통일 문제와 어떤 연관이 있는지에 대해 통일정책과 통일 역량 강화의 측면에서 나누어 고찰했다. 전자에 포괄되는 주제로는 통일국가의 미래상, 북한경제의 유사성 및 변화가 있다. 후자와 관련되는 주제로는 남북교류협력, 북한이탈주민정책, 통일교육에 대한 함의를 다뤘다. 통일국가의 미래상과 관련하여 사회적경제는 통일경제의 부작용에 대한 완충기제로 작동할 수 있을 것으로 예상된다. 사회적경제는 자본주의의 발전에 따라 제기되는 사회적 문제를 해결하고자 하는 보완적 성격의 경제활동으로 이해된다. 따라서 향후 자유시장경제 방식의 통일이 진행되는 경우, 남한 자본주의의 문제점이 전 한반도로 확산되는 부작용에 대한 대안적 해결방안으로 작동할 수 있을 것으로 기대된다. 사회적경제가 북한경제, 나아가 사회주의 경제와 유사성이 있는지에 대해서는 논란이 있다. 향후 이에 대한 연구 성과에 따라 북한경제의 변화를 추동하는 동력으로서 사회적경제의 영향력을 가늠할 수 있을 것이다. 남북교류협력과 관련해서는 우선, 교류협력이 재개되는 경우 사회적경제기업의 참여를 어떻게 추동하고 지원할 것인지에 대한 대안을 내놓을 필요가 있다. 일반 기업 또한 사회적경제 관점을 활용해 북한 진출에 나설 수 있을 것으로 예상할 수 있고, 이 때 중요한 사회적경제의 키워드는 BOP 시장이다. 사회적경제는 북한이탈주민을 취약계층으로 자리매김하고 있는데, 향후에는 적극적으로 사회적경제의 창업의 주체로 육성할 필요성이 있다는 점도 제기하였다. 통일교육과 관련해서는 대상, 주체, 내용과 관련한 시론적 차원의 접근을 정리하였다. 사회적경제의 부상이 북한학 연구에 미치는 영향에 대해서는 더 많은 새로운 상상력의 발휘가 요구된다.

In Korea, the soil series derived from sedimentary rocks are classified into seven soil series of coarse loamy soil such as Dain, Danbug, Dongam, Imdong, Jeomgog, Maryeong, and Yonggog; seventeen soil series of fine loamy soil such as Angye, Anmi, Banho, Bigog, Deoggog, Dogye, Dojeon, Gamgog, Gugog, Jincheon, Maji, Mungyeong, Oggye, Samam, Yanggog, Yeongwol, and Yulgog; six soil series of fine silty soil such as Goryeong, Bonggog, Juggog, Gyeongsan, Yuga, and Yugog; and four soil series of clayey soil such as Mitan, Pyeongan, Pyeongjeon, and Uji. All thirty-four soil series have different drainage rates and topography. However, the soil texture depends on the parent rock. The buffer functions in GIS (Geographic Information System) techniques were used to calculate adjacent soil series from a soil series. The length of the adjacent soil series was adjusted because a side of the buffer area was one meter long. The cluster analysis was conducted using the CCC (Cubic Clustering Criterion) method, in which the number of clusters is calculated based on the individual soil series ratio. Soil survey has been carried out since 1964 as "The reconnaissance soil survey", and 1:5,000 detailed soil survey was completed in 1999 with a five-years plan in Korea. Today, all the soil survey information has been computerized. GIS techniques were used to establish a digital soil map; however, there have not been any studies to interpret pedogenesis using the GIS technique. In this study, the area of the adjacent soil series were obtained using the GIS technique. The area of the adjacent soil series can be calculated based on the information area. The similarities of soil originated from sedimentary rocks were estimated using the length. As a result, the distribution of grain size was different based on the types of sedimentary rocks and the location. The clusters were distinguished into limestone, sandstone, and shale. In addition, the soil derived from shale was divided into red shale and gray shale. This means that quantitative interpretation of the catena and this established method can be used to interpret the relationship between soil series.
