Recently, learning how to learn is a matter of concern among many pedagogists and become the important subject matter of school education. That's why there are many learners who fail to get good results compared with their potential abilities and efforts, as well as the necessity to educate independent and self-determined learner by teaching learning strategies that can help leaners to get new information and skills by themselves in an information-oriented society was emphasized. Therefore, this study is to utilize the learning strategy in order to improve the learners study skills, and grope for the method of self-directed learning about the social studies centered on the learners. And, it is to utilize the reciprocal teaching with the learning strategy for improving the learners study skills. Also, it is to make the learners induced to participate in the teaching for social studies actively, grafting the characteristics of web on the reciprocal teaching. According to this intent, this study was developed as three steps. As for the first step, it investigated the reciprocal teaching, a teaching-learning theory to apply to the program, and the theoretical background about web utility in the social studies. On the second step, it embodied the reciprocal teaching-learning system about the we-based social studies that will be available in the self-directed learning centered on the learners. Lastly, it analysed the change of recognition about the learners social study skills and the learning the social studies after applying the materialized website to the actual lesson.

어장관리해역으로 지정된 옹진군의 수질 및 퇴적물 환경 특성을 파악하기 위하여 2011년에 4개 도서(장봉도, 자월도, 영흥도, 백령도)를 대상으로 조사를 실시하였다. 수온은 $9.49{\sim}24.14^{\circ}C$로 계절변동 특성을 잘 나타내었고, 염분(23.19~31.49)과 용존산소(5.48~9.36 mg/L)는 수온과 역상관성을 보였으며, 화학적산소요구량(COD)은 평균 1.57 mg/L로 전체적으로 양호한 수준이었다. DIN과 DIP는 각각 0.111~0.666 mg/L, 0.002~0.043 mg/L의 범위로 전 정점에서 낮은 분포를 보였고, 엽록소 a의 농도는 $0.02{\sim}8.07{\mu}g/L$ 범위로 서해의 다른 해역보다 낮았다. 퇴적물의 입도 분포는 모래와 실트가 각각 56.7 %, 34.6 %로 우세하였고, 분급은 불량하였다. 퇴적물의 화학적산소요구량과 강열감량은 각각 $1.00{\sim}11.03mg/g{\cdot}dry$, 0.72~5.29 %의 범위로 시 공간적으로 유사한 경향을 보였다. 총유기탄소와 총질소의 C/N ratio는 8.17~17.97 범위로 하계에 육상기원과 해양기원에 의한 영향이 혼재하는 것으로 나타났다. 표층퇴적물의 미량금속 오염도 평가를 위해 농집지수($I_{geo}$)를 계산한 결과, Cr과 As를 제외한 나머지 금속원소에 의한 오염은 없는 것으로 판단된다. 이러한 연구 결과는 본 연구지역이 전체적으로 양호한 수질을 보이며, 유기물과 금속원소에 의한 표층퇴적물의 오염이 없다는 것을 보여준다. To improve productivity of aquaculture animals with management of culturing grounds, survey of mariculture management area in Ongjin-gun about water quality and sedimentary environment had been conducted on June, August and November in 2011. Water temperature in surface and bottom waters ranged from 9.49 to $24.14^{\circ}C$. Salinity and dissolved oxygen concentrations were in the range of 23.19~31.49 and 5.48~9.36 mg/L, respectively, depending on the variation of water temperature. The average concentration of COD was 1.57 mg/L and the concentrations of DIN and DIP showed entirely low level. As the result of grain size analysis, sand(56.66 %) and silt(34.60 %) were predominated. The Mz of sediment showed a variation of 2.59 to $6.62{\O}$ and sorting appeared to be poorly sorted. The concentrations of COD and IL in surface sediment ranged from 1.00 to $11.03mg/g{\cdot}dry$ and 0.72 to 5.29 %, respectively, which showed relatively good positive correlations. On the environmental assessment of trace metals in surface sediment, geoaccumulation index ($I_{geo}$) class indicated that sediments were not contaminated by most of metallic elements except Cr and As. Our result implies that this study area showed good water quality and sediments were not polluted by organic matters and metallic elements.

Objective : This study aimed to ascertain the effect of interpersonal sensitivity/resilience on depression and anxiety in firefighters whose frequency of exposure to traumatic events is high. Method : A survey was performed and data related to 75 firefighters were analyzed. Questionnaires included the Beck Depression Inventory (BDI) and Impact of Event Scale-Revised (IES-R). To assess the susceptibility or protector roles with respect to psychopathology, the Interpersonal Sensitivity Measure (IPSM) and Conner-Davidson Resilience Scale (CD-RISC) were used. Results : The personality characteristic, interpersonal sensitivity (IPSM) showed a significant positive correlation with depression (BDI, r=0.557, p<0.001) and posttraumatic stress symptoms (IES-R, r=0.316 ; p<0.001). In contrast, resilience and symptom parameters (BDI, IES-R) were negatively correlated with each other, but not statistically significant. However, an adaptive factor for change, a third sub-factor of CD-RISC, had significant negative correlation with depression and anxiety symptoms (BDI, r=-0.275, p<0.005 ; IES-R, r=-0.254, p<0.005). Conclusion : The results of the present study showed that some personality traits may act as vulnerability or protective factors with respect to the psychopathologies of depression and anxiety.

Occlusal splints have been widely used in dentistry for treatment and diagnosis of signs and symptoms related to dental occlusion. The autor studyed the effect of occlusal splint on masticatory movement of young adult men (mean age 23.8 yrs.). Who had worn. occlusal splint for 1 week. The result were as follows: 1. Lateral movement of the mandible during mastication could be increased after wearing occlusal splint for 1 week. 2. Vertical movement of the mandible during mastication was increased after wearing occlusal splint for 1 week. 3. Maximum opening velocity of the mandible during mastication was increased after wearing occlusal splint for 1 week. 4. Mandibular movement during mastication was more affected by chewing of hard foods than of soft foods following occlusal changes. 5. Steepness of the anterior guidance affected several aspects of masticatory movement. 6. Masticatory movement of the mandible became more regular after wearing occlusal splint for 1 week.

Since the concept of a direct contact between bone and implants, without interposed soft- tissue layers, was reported by Dr. $Br{\aa}nemark$, there has been increasing necessity for correct under-standing of bone-implant interface and surrounding tissue response. Beside quality of bone, surgical technique, load applied to implants, one must consider implant materials, design and surface characteristics to obtain osseointegration. In this study HA plasma-sprayed implants, TPS implants and $Al_2O_3$ implants were inserted into the alveolar bone of dog and tissue response was observed with radiograph, stereoscope, light microscope, and scanning electron microscope. Results were as follows : 1. There was rapid and active bone formation in the region adjacent to HA plasma-sprayed implants but in the deep supporting bone only slight bone formation was seen. 2. There was considerable lamella bone formation in the region adjacent to TPS implants and the deep supporting bone became more compact. 3. There was some gap and sclerosing bone formation in the adjacent region of $Al_2O_3$ implants, but there was irregular new bone formation in the deep supporting bone. Therefore, it seems that $Al_2O_3$ is not adequate for osseointegrated implants.

There is no established treatment for esophageal carcinoma with metastasis. For the metastatic esophageal squamous cell carcinoma, chemotherapy or best supportive care according to patient's performance status are accepted as an available treatment. We report a case of complete remission after concurrent chemoradiotherapy for esophageal squamous cell carcinoma with metastatic lesion in 5th thoracic vertebrae. A 57-year-old man with ongoing dysphagia and weight loss was admitted to our hospital. On the endoscopic and radiologic imaging evaluation,the patient was diagnosed as a squamous cell carcinoma of esophagus with solitary metastatic lesion in 5th thoracic vertebrae. The patient was treated with combination chemotherapy (5-fluorouracil (5-FU) and cisplatin) and concurrent radiotherapy for two months to relieve dysphagia. Because metastatic lesion in thoracic vertebrae was located near the primary esophageal tumor, the metastatic lesion could be included within the radiation field. After concurrent chemoradiotherapy, consecutive 4 cycles of chemotherapy had been carried out. Primary esophageal tumor with metastatic lymph nodes and metastatic lesion in 5th thoracic vertebrae disappeared on follow up computed tomography (CT) and positron emission tomography-CT (PET-CT). Follow up endoscopic biopsy revealed no remnant malignant cells at previous primary cancer lesion.

자궁내막증 진단을 위한 생표지자의 유용성

김선영,이병석,Kim, Sun-Young,Lee, Byung-Seok 대한생식의학회 2010 Clinical and Experimental Reproductive Medicine Vol.37 No.1

진단적 복강경을 하지 않으면 자궁내막증의 진단이 불가능하다는 점은 의사들이 해결해야 할 과제 중 하나이다. 아직까지는 자궁내막증을 진단할 수 있는 획기적인 표지자가 없기 때문에 CA-125 같은 종양 표지자의 혈중 농도를 측정하였으나 진단 도구로 이용하기에는 한계가 있다. 이러한 이유로 초기 자궁내막증을 진단할 수 있는 방법을 연구하기 위한 여러 시도들이 있었는데 특히 자궁내막증 1, 2기 환자에서 병의 초기 상태에 복강경적 치료를 하였을 경우 자연 임신 성공률이 2배 가까이 높은 것으로 보고되었기 때문에 불임 여성에 있어 자궁내막증의 진단 시기는 임상적으로도 그 중요성이 매우 크다고 할 수 있겠다. CA-125는 자궁내막증 환자의 추적관찰에 있어 특이도가 높은 편이며 효용성이 있는데 특히 수술적 치료 후 장기적으로 병의 활성 혹은 재발을 평가하는데 있어 유용하다. 무작위적인 임상 연구 결과 자궁내막증과 관련된 불임이나 통증은 수술적 치료시 분명한 이득이 있는 것으로 보고된 바84 자궁내막증은 적절한 진단과 치료가 중요한 질환이라는 점을 다시 한번 상기해야 한다. 또한 병의 진행에 따른 여러 면역학적인 변화들이 확인되면서 자궁내막증의 진단에 있어 면역학적 표지자의 중요성이 부각되고 있다. 그 중에서도 복막액이나 혈청 내 사이토카인은 진단 도구로서 그 가능성에 주목을 받고 있으며 이에 대한 대규모 연구가 추후 필요할 것으로 사료된다. 최근의 면역학적 발견과 DNA 기술 발전은 자궁내막증의 진단에 있어 핵심적인 screening 도구의 발견에 일조할 것이며 이러한 기술적 발전을 근간으로 하여 머지 않아 획기적인 표지자가 개발될 것으로 기대한다.

Genomic DNA isolated from two geographical ark shell (Scapharca subcrenata) populations was amplified several times by PCR reactions. The ark shell population from Daecheon (ASPD) and from Wonsan (ASPW) in the West Sea and the East Sea of Korean Peninsula, respectively, obtained. The seven arbitrarily selected primers OPA-05, OPA-11, OPB-09, OPB-11, OPB-14, OPC-18 and OPD-07 were shown to generate the loci observed per primer, shared loci by each population, specific loci, unique shared loci to each population and shared loci by the two populations which could be clearly scored. Here, 862 loci were identified in the ASPD population, and 1,191 in the ASPW population: 137 specific loci (15.9%) in the Daecheon population and 84 (7.1%) in the Wonsan population. 407 shared loci by each population, with an average of 58.1 per primer, were observed in the ASPD population. 473 shared loci by each population, with an average of 67.6 per primer, were identified in the ASPW population. The numbers of specific loci in the ASPD and ASPW population were 137 and 84, respectively. Consequently, the average bandsharing value of individuals within the ASPW population was much higher than in the ASPD population. The bandsharing value between individuals' no. 08 and no. 13 was 0.628, which was the highest measured between the two geographical populations. The dendrogram obtained by the seven primers indicated three genetic clusters: cluster 1 (DAECHEON 01-DAECHEON 11), cluster 2 (WONSAN 12 and 14) and cluster 3 (WON SAN 13, 15, 16, 17, 18, 19, 20, 21 and 22). The genetic distance between the two geographical populations ranged from 0.043 to 0.499. Especially, individual no. 10 of Daecheon population was most distantly related to no. 14 of Wonsan population (genetic distance = 0.499).

Refinery plant producing petroleum products from crude oil has significantly contributed to the creation of the national interests as a leading engineering industries. However, domestic Engineering Procurement Construction (EPC) companies are facing heavy competition for orders. Domestic EPC companies as EPC contractors are faced with some problems such as undertaking responsibility for FEED packages produced by other FEED companies. But domestic EPC contractors are unfamiliar to development and validation of FEED packages. It causes poor profitability and lower competitiveness of domestic companies. It is necessary for domestic companies to have capability to perform FEED activities in order to overcome these limitations instead of focusing on EPC phase after FEED phase. The systematic procedure is needed to perform the FEED activities, however, there are present difficulties on it due to the lack of experience in FEED packages development which require various engineering knowledge of chemical process, mechanics, electrics, instrumentation, civil engineering. This study has applied systems engineering method which is multi-disciplinary approach to derive and verify the solution to meet the customer's needs when the complex system is developed to task execution process development of FEED activities for refinery plant. The problems that may occur in the future were identified in advance by taking into account the various stakeholders and system context through the application of systems engineering. It helps to develop the task execution process systematically. The developed task execution process of FEED activities is planned to make effectiveness verified by engineering professionals experienced in FEED and continually enhance this process by field application.
