This research wanted to examine what narratives and discourse were being formed in web drama contents young generations were going crazy about. To understand the characteristics of such love epics and to know what narratives were being formed based on narrative structures and comments, this research specifically used the web drama produced up to the season 4 for the first time in Korean web drama history with a large number of accumulated views. It was found that the narratives of the drama composed the romantic relationships of four couples as independent episodes, and realistically highlighted separations and reunions of those couples, and suggested concrete methods to solve agonies and conflicts they would experience in such relationships. And, in user comments, there emerged relational narratives confusing friendship and love between partners of opposite sex, narratives regarding the third person as enemy, and narratives on typical sex roles in such romantic relations. And, the culture seeking subjective love style and sharing and sympathizing with the love histories also appeared.

In this study, we analyzed the descriptions of the electron movement model and the oxidation number change model presented in the 2009 revised curriculum and textbooks. We also investigated chemistry education major teachers' conceptions of limitations of each model. The electron movement model and oxidation number change model were presented in the curriculum and the textbooks. However, hybrid model was also presented which fail to grasp the limitation of each model. The hybrid model explains redox reactions of covalent bond compounds by electron movement model or even if it explains redox reactions by oxidation number change model, this explanations have the problem of confusing the virtual electron movement with the actual electron movement. A questionnaire and interviews were conducted to investigate chemistry education major teachers' perceptions of redox reactions. As results, many teachers did not recognize the limitations of each model and had difficulties to distinguish redox reactions from acid-base reactions because of the hybrid model.

This study is to review the historical documents about Cinnamomum camphora SIEB. in Goryeo and Joseon Dynasty. First of all, we defined it's feature and used case by the most appropriate word 'Jang(樟)' meaning Cinnamomum camphora SIEB. We also discovered some illusions and should suggest a new possibility. First, we analyzed the definition and examples of Cinnamomum camphora SIEB. and come to the conclusion that 'Jang(樟)' seems to be the most appropriate word. Second, we confirmed that Cinnamomum camphora SIEB. grew in extralimital area. It is believed that it's because of making a mistake. Third, we confirmed that it is confused Cinnamomum camphora SIEB. with Koelreuteria paniculata in Yi, Gyu-Gyeong's records. However, it's required to verify the other cases of the Cinnamomum camphora SIEB.'s records. We expect a follow-up study about it by classifying modern feature and comparing literature matching.

Primary pulmonary artery sarcoma is a rare malignant tumor arising from the pulmonary artery. Diagnosis of primary pulmonary artery sarcoma is quite difficult and the conditon is often misdiagnosed as a more common disease, such as a pulmonary embolism. PET can help in diagnosing a pulmonary artery sarcoma due to the increased uptake of $^{18}F-FDG$ in the area of the tumor. However, the poor anatomic resolution of PET has limited its clinical applications in pulmonary vascular disease. The recently developed PET/CT is the fusion of PET and CT that improves the anatomical resolution of PET. We report a case of a primary pulmonary artery sarcoma mimicking a pulmonary embolism that was diagnosed with PET/CT and confirmed with a surgical resection.

청각의 중요성은 새잠스럽게 말활 필요도 없고 농아가 말못하는 것은 누구나 다 알 수 있는 사실입니다. 그러나 음을 하나하나 습득하고 단어를 하나하나 반복하면서 언어습득을 시작하는 유년기에 있어서 청각은 더욱 독특한 역활을 합니다. 조국에 돌아와서 일하기 시작한지 일년이 조금 넘었으나 최초부터 우리 연구소에 찾아오는 어린이가 구주제국보다 훨씬 연소하고 또 수가 훨씬 많은 데 놀랐습니다. 그 중 대다수가 조음장애라든가 언어지연입니다. 더욱 놀라운 점은 이러한 장애가 정상지능의 어린이에게 많은 것입니다. 일반상식으로 어휘력과 발표력이 부족한 어린이들은 정신지체아와 혼동하게 됩니다. 연구소에 진단받으러 오는 어린이들을 체계적으로 청각 검사를 한 결과를 슬라이드를 통해서 말씀드리겠습나다. 검사받은 어린이 중 50-60%가 청각에 이상이 있는 것이 발견되었습니다. 동반한 어머니들은 너무나 놀라서 "우리 아이는 검사를 받았어요! 모두 정상이라고 그랬어요" 이 엄마 말씀도 정당하고 전검사도 정당활 것입니다. 그러나 이러한 어린이들의 문제는 특수합니다. 즉 경도난청에다 또 일시적 난청이기 때문에 명시에 생활하는 데는 큰 지장이 없고 때에 따라서는 청각이 거의 완전히 회복되고 또 몇 주후에 감기가 들거나 하면 다시 난청이 되는 것입니다. 이러한 난청문제가 일년에 3-4번씩 반복되어 어린이가 만 3-4세가 되면 약 1년간 청확한 음을 청취못한 셈이 됩니다. 조석에 기온차가 대단한 계절, 난방의 발달로 인하여 실내는 영상 24도이고 문 한겹만 열고 나가면 영하 10도 그 차이는 34도, 거리로 나가면 일산화탄소를 뿜고 쾌주 하는 차량, 버스나 트럭에셔 나오는 연기는 키가 작은 어린이 코속으로 직통하고 에어컨 시스댐으로 난방.냉방하는 지하상가, 백화점, 지하철 기타 대건물에는 바이러스 만연의 적절한 곳이 됩니다. 생리적 저항력이 없는 어린이들은 이러한 공해와 생활조건의 제일희생자가 되는 것입니다. 엄마들이 "얘는 감기, 비염, 편도선을 달고 삽니다...." "얘는 코감기, 목감기 번갈아 가면서 하도 앓고 있어서 양약율 중지하고 현재 한약을 먹고 있습니다." 이러한 역경은 극복할 수 있는가\ulcorner 질병의 메카니즘은 어떻게 작용되는가\ulcorner 등등을 육미회 센타에서 체험한 사례를 가지고 말씀드리고자 합니다.

This study investigated both elementary and middle school students' abilities of reading scales and students' conceptions of measuring instruments and units. Seventy two students with 5th grade, sixty nine students with 7th grade, and eighty students with 9th grade were participated. Performance tests and written questionnaires were used. To assess their scale reading abilities, individual performance test was used. Every student should measure length of an envelope, temperature of water, volume of water, etc. And to find out students' conceptions related with measuring instruments and units, written questionnaires with pictures and photographs were used. Some of the students' abilities of reading scales were considerably poor. The results of a two-plate-balance and measuring-cylinder were worse than those of a ruler, a spring-balance, and a thermometer. Many of the students had misconceptions related with measuring instruments. Some of them did not know exactly the meaning of volume, or mass, or force. So they did not know what to measure with the measuring instruments. Also students were confused with several units of volume, force, weight and mass.

School adjustment has been a popular topic among scholars in multicultural family studies, and they commonly report poor adjustment of children from multicultural families. However, without subjects for comparison, these findings may be considered premature. This study investigated school adjustment of children from multicultural families by comparing their adjustment level to that of children from families with Korean parents. By using the matching procedure, this study examined whether children's multicultural family background attributes to their school adjustment with children's observable characteristics paired and matched. For the analyses, the first and fourth wave of Korean Children and Youth Panel Study data were used. When the school adjustment level was examined before the matching procedure, the school adjustment level was indeed lower among children of multicultural families, and their family status was a significant predictor of school adjustment. However, when two groups were paired and matched using matching, the family background had no significant effect, indicating that school adjustment is not predicted by their multicultural family status. Implications for research and practice are also discussed in the paper.

We report a case of bizarre parosteal osteochondromatous proliferation of the right femur in an 18-year-old man. Roentgenograms showed a calcific mass attached to the underlying cortex with a broad base. Histologically, the lesion showed hypercellular cartilaginous tissue with maturation into trabecular bone, which contained spindle cells and lymphocytes in the intertrabecular spaces. Bizarre parosteal osteochondromatous proliferations are a form of heterotopic ossification and should not be mistaken for osteosarcoma or chondrosarcoma.

This paper is to show the character coding rule in computer and information equipment etc to improve the transmission efficiency in telecommunications. In the transmission system, the transmission efficiency can be increased by applying the proper character coding method. In datalink layer, HDSL ptotocol use FLAG byte to identify the frame to frame which consists of data bit stream and other control bytes. FLAG byte constits of "01111110". When data bit stream consist of the consecutive 5-bit "1" after "0", the decoder can not distinguish whether the data bit sequence is flag bit stream or data bit stream. To solve the problem, when the line coder in transmitter detects the consecutive 5-bits "1" after "0" in the input data stream, inserts violently the "0" after 5th "1" of the consecutive 5-bit "1" after "0". As a result, when the characters are decoded with the above procedure, the efficiency of system should be decreased. This paper shows the character code rule to minimize the consecutive 5-bits "1" after "0" when the code is given to each characters.

The primary purpose of this treatise is to suggest the solutions as follows for the errors concerning the triangle determination and congruence in every Korean mathematics textbook for 7th graders: showing that SsA, along with SSS, SAS, ASA, should also be included as the condition for triangle determination, congruence and similarity; proving that contrary to what has been believed, minimality applies only to congruence and similarity but not to determination; examining related Euclidean propositions; discussing the confusion about the characteristics of determination and congruence; and considering the negative effects of giving definite figures in construction education. The secondary purpose is to analyze the significance of triangle determinant that is not dealt with in either Euclid's Elements or the text books in the U.S. or Japan, and suggest a way to effectively deal with triangle determination and congruence in education.
