The self-segmentation of Seoin(西人) School and the appearance of Soron(少論) School in the 17th century Joseon society has an important meaning in the political history. Soron School(少論學派) had quite different line in their thought and public position from the Noron(老論) School represented by Song Shi-yeol. With such thought and position, Soron School added a vitality to the barren climate of Joseon intellectual society and soon became an important school of it. Especially, the senior leaders of early Soron School shared the culture of discussion and dialogue which was represented by the phrase, "the forest of debate and the hill of argument". Accordingly, Soron School could form an unique academic tradition which was different from other schools. For instance, Park Se-dang(朴世堂), Nam Gu-man(南九萬), Yoon Jeung(尹拯) and Park Se-chae(朴世采) had relatively flexible Conception of Heresy; which was in the same context with the academic position of Soron School that allowed diverse approaches to truth each as the path of justice. Furthermore, the leaders of Soron School continued dialogue and discussion on the wide range of current issues. They deeply sympathized with the Tangpyeong-ron(蕩平論), which was to appoint important government positions equally from multiple schools. They thought that the Tangpyeong-ron(蕩平論) was to avoid the harmful influence of conflicts between schools, the Bungdang(朋黨), and tried to tune and compromise the different opinions of different schools. In fact, the "Hwanggeuk Tangpyeong-ron" (皇極蕩平論) submitted by Park Se-chae was the summarization of the discussions shared by the Soron School leaders. Consequently, the seniors of Soron School practiced their philosophy that "the true academic practice is the communication" by keeping the dialogue with other schools while respecting the difference of each other, rather than staying comfortably in the closed academic fence of uniformity. Such communicative academic practice adopting discussion and dialogue had been succeeded to the second generation of Soron School and it remained as an unique academic tradition of Soron School.

As the institute of education teaching radiologic technology in Korea, different from others, junior college is the only institute which has been managed for it as a two-year educational course for 27 years since 1963 when it was established for the first time in our country irrespective of the needs of the times. But according to the development of medical equipment, variety of medical skill, increase of medical demands now a days, the supply of radiologic technology in modern medicine not only makes it advance as an inevitable factor but also broadens the area of its business systematically. Therefore, we got the following results after we had considered the necessity to lengthen the term of education and searched for the most reasonable way. 1. The term of study of the radiologic technologists in junior college must be lengthened to 3 years from 2 or 3 years regulated in the law of education. 2. In three-year curriculum, the subjects like basic medical science, science and engineering and ultramodern science, etc., which are lated to the new radiologic science must be taught in the junior colleges, and hospital practice also must be a compulsory subject in curriculum. 3. As the school years becomes longer, a lot of programs to make the study effective must be searched, researched and propelled forward.

This study is to give management state information about changes of income and net profit due to the fluctuations of chestnut prices to someone who will manage a chestnut orchard or has been managing a chestnut orchard in the market opening time. This study, hence, evaluated 133 households who manage a chestnut orchard at Jin-ju, San-cheoung in Gyeong-nam, Gu-rae in Jeon-nam, Gong-ju, Bu-yeo, and Cheoung-yang in Chung-nam. This study analyzed three scenarios by chestnut prices and by tree ages to provide informations for working expenses, production cost, income and net income to cultivators. In case of chestnut of one thousand won, the income of chestnut trees generated from nine ages and the net income is obtained from ten ages and turned into deficit from twenty-eight ages. In case of chestnut of one thousand and five hundred won, the income of chestnut trees generated from seven ages and the net income is obtained from nine ages. In case of chestnut of two thousand won, the income of chestnut trees generated from six ages and the net income is obtained seven nine ages. We calculated out labor costs and material cost and figured out management cost by tree ages. Namely two man and twenty woman are employed in harvesting 3,000 kg by hectare from ten till eighteen ages maximum harvesting seasons. Material cost is fertilizer cost, agricultural chemicals cost and seeding cost.

Organic-inorganic hybrid mesoporous materials were prepared by co-condensation of organosilanes with tetraethyl orthosilicate (TEOS) or 1,2-bis(triethoxysilyl) ethane (BTSE). Their removal capability of volatile organic compounds (VOCs) in the air was evaluated and compared with that of inorganic hydrophilic mesoporous material, SBA-15 that was prepared with TEOS only. It was found that the increased hydrophobicity of mesoporous materials due to the presence of organic group, could enhance the VOCs removal by adsorption in the air. An organic-inorganic hybrid material prepared by the co-condensation of BTSE/phenyl triethoxysilane (90/10 by weight) was a typical example of superior adsorbent. It was also observed that these organic-inorganic hybrid materials can be utilized as absorbents for the removal of oil dispersed in water.

The changes in major moth populations were monitored by sex pheromone traps in pear orchards at Yuseong-Gu, Daejeon from 2008 to 2010. Among four major moths, Grapholita molesta and Caposina sasakii occurred most frequently. Their occurrences peaked 2 to 3 times during the growing season from May to September. G. molesta was exceptional, occurring until September. For the environmentally-friendly control of these moths, 9 control materials including insect pathogenic bacteria and environmentally-friendly agricultural materials, were examined on the larva of 4 kinds of moth and sprayed on pear leaves in the field. As the generalized results of bioassay, Bacillus thuringiensis subsp. kurstaki and Sophora flavescens extract were shown to have better control effects than any other control material.

Purpose: Lymphoma originated from mucosa associated lymphoid tissue(MALT) is most common in gastrointestinal system, and rarely found in salivary gland, thyroid, bronchus or orbit. We experienced a case of MALT lymphoma which was originated from conjunctiva and involving lower eyelid without metastasis. Methods: A 40-year-old man suffered palpable mass on right lower eyelid without pain. Orbital computed tomographic and ultrasonographic findings showed a conical mass($1.9{\times}1.2{\times}0.9cm$ size) inside lower eyelid. The mass was completely excised under local anesthesia and histopathological examination was followed. Results: Microscopic finding showed a multiple follicular colonization. In the follicle, small lymphocytes and plasma cells differentiated to centrocyte-like cell, monocyte B cell, plasma cell were diffusely infiltrated. Immunophenotyping was preformed on fixed section. The majority of the small cells were immunoreactive for the B cell marker CD20. Based on the typical histological findings supported by immunostaining, the mass was defined as MALT lymphoma. After excision, SPECT, abdominal CT was carried out and there were no evidence of extraorbital disease. Conclusion: Biopsy and pathological examination should be performed in patients who complain palpable mass on lower eyelid because of possibility of MALT lymphoma. Although MALT lymphoma is rarely metastasized, it is necessary to evaluate the extraorbital involvement using SPECT or other radiologic exams. For detecting extraorbital involvement, periodic follow-up examination is need.
